Learn how to make a Valentine mailbox craft with printables and custom decorations!

I’m convinced that crafting is a superpower. I love seeing things in a store and thinking … KNOWING, “I can make that!” Do you ever think that? I hope so, because YOU CAN! Believing in and challenging yourself is powerful, but the Super part is making your own one-of-a-kind creation. That’s how I made my 3D layered paper cut flower after falling for an expensive version at the mall. I saw a cute decorative mailbox at a craft store and guess what I thought? It sure looked like I could recreate the mailbox’s pieces using simple shapes in cardstock. And making it open up for Valentine mail would be fun! I got to work and am IN LOVE with the result that I’m sharing with you. I’ll show you the basic steps to make a Valentine mailbox craft and share some personalization ideas!

My basic Valentine mailbox craft is easy to make! We’ll cover how to add score lines to cardstock, which is a great way to create 3D shapes from flat materials like paper. I’ll also share one of my favorite craft glues to use on your tabs. It’s perfect for applying just the right amount of sticky to small spots!

Of course, the best part of a mailbox is getting cards in the mail! I’ll show you some secrets to create a flag that rises smoothly (Hint: see that mini brad on the supply list?) and a front door that’s easy to open and close.

To make your Valentine mailbox craft officially magical, we’ll create a sleepy unicorn version in the tutorial! I’ll show you the best spots to attach our new friend’s horn, ears, and eyes to complete their look. The mailbox is similar in size to a childrens’ shoebox, so placement is important.

Now, I always feel loved when I get cards in the mail, and we want our unicorn to feel the same. So we’ll make some pretty rolled paper flowers with a quilling tool. You can add whatever you like in any colors! Vinyl hearts, glitter stars, or even a name would be perfect!

My FREE Valentine mailbox craft download includes adorable printable cards. They feature our cute animals from our layered vinyl color changing cup project and encouraging sentiments sure to spread the love. You do need a color printer and a Cricut Maker or Cricut Explore series to use the Print Then Cut feature

You can cut the cardstock by hand, but a Cricut cutting machine will help this go so much faster! If you use a Cricut, you’ll also want a green machine mat, Fine-Point Blade, Scoring Stylus (or Scoring Tool), scraper, and brayer.

If you choose to add paper flowers, you’ll need a hot glue gun and glue sticks to secure them to the mailbox. Also, a weeding tool will help with vinyl decorations

The first step is to download my Valentine Mailbox Craft files from my free resource library — they're design #371.

TIP: If you are not sure how to upload an SVG cut file to Cricut Design Space, watch this helpful video training series I made. If you are on an iPad or iPhone, here is how to download and upload SVG files to the Cricut Design Space app. This is what my Valentine Mailbox Craft SVG files look like when they are uploaded to Cricut Design Space.

Valentine Mailbox Craft Upload SVG to Cricut Design Space

As you can see, there are two SVG files. One is for the basic mailbox and one includes the pieces for the unicorn version.

I’m going to show you how to make my adorable Unicorn Valentine Mailbox Craft, so I will keep both SVGs on my Canvas. If you only want to make the basic version and add your own decorations later, you don’t need to upload the unicorn file.

The first thing we need to do is ungroup all the pieces. To do this, select the mailbox SVG and click “UnGroup” at the top of the Layers Panel on the far right. Then click on the unicorn SVG and do the same.

Valentine Mailbox Craft Ungroup SVG in Cricut Design Space

The reason we ungrouped is so that we can change some of our Cut lines to Score lines. The Score lines will make it easier to fold the cardstock after it’s cut. There are eight Cut lines that need to be changed. These should appear as black lines or black outlines in the Layers Panel.

You can select and change these one at a time or all at once, which is what I will do.

In the Layers Panel, start from the top and select the first line we want to change to Score by clicking on it.

Now, hold the SHIFT key and click on the other layers that need to be changed. There are eight total: the two tabs on the unicorn horn, the two unicorn ear tabs, the tabs for the front and back doors, the middle of the open tab, and the folds of the base of the mailbox.

Select the score layers in the layers panel of Cricut Design Space

With all of the indicated layers selected, click in the drop-down field under “Operation” in the top menu where it says “Basic Cut” and scroll down and click on “Score.”

You will notice that all the selected layers that said “Basic Cut” have changed to “Score” in the Layers Panel.

Click the operation menu and select score

Now we need to Attach each Score line to the design piece it belongs to.

In the Layers Panel, start at the top and click on each layer and its corresponding score line(s). With both selected, click “Attach” at the bottom of the Layers Panel.

Valentine Mailbox Craft Attach Score Layer to Cut Layer

Repeat these steps until all the Score lines are attached to their corresponding layers. You might notice that when you Attach the Score lines to the outer part of the unicorn ears, the pink piece seems to disappear, but that’s not the case. When you Attach the Score line to the outer ear piece, the pink layer moves to the back, but it’s still there. You can see this if you look in the Layers Panel.

Whether you are using 8.5" x 11" or 12" x 12", this project is ready to cut without resizing.

NOTE: If you would like to make a smaller mailbox, you can click "Select All" in the top menu and use the resize handle to adjust the design's size. It’s important to select all the pieces together so they change in proportion to one another.

If you want to add even more details to your mailbox, Cricut Design Space has many fun shapes you can use for decorations. To see all the options, click on "Shapes" on the left side of your Canvas.

Select shapes icon to add shapes to the canvas in Cricut Design Space

I made another mailbox covered in rainbow-colored hearts cut from permanent vinyl. First, I selected the heart shape to bring a copy on to my Canvas. I adjusted the heart's size to fit my project by clicking and dragging the resize handle. You can also change the dimensions in the top menu using the Size fields.

Once I was happy with the heart size, I duplicated it by right-clicking my mouse on it and scrolling down to “Duplicate.” You can also do that by clicking “Duplicate” at the top of the Layers Panel.

Then, I changed the color of each heart. I selected them one at a time, clicked on the color picker box next to “Basic Cut” in the top menu, and then selected the color I wanted. You can use these steps on any shapes to decorate your mailbox!

Color menu in Cricut Design Space


Click "Make It" in the upper right corner. If you are using a Maker 3 or Explore 3, you will be asked if you want to cut your designs without a mat, with a mat, or in multiple ways. Select "On Mat" and click "Continue."

Valentine Mailbox Craft Design Space Select On Mat

If you are making the unicorn mailbox like me, you should see seven (7) mats on the “Prepare” screen.

NOTE: If you see any additional mats, you may not have attached all of your Score lines to their corresponding layers. If that’s the case, simply click “Cancel” to return to the Canvas and fix that.

Number of Mats on Prepare Screen in Cricut Design Space for Valentine Mailbox Craft

If you are using 12" x 12" cardstock, you don't need to change anything on the mats. Click "Continue" to select your material.

If you are using 8.5" x 11" cardstock (or any other size), you need to change the size of your material. On the left side of the screen, click on the arrow under "Material Size" to select the appropriate paper size for each mat. Once you're finished making changes, click back on the first mat and click "Continue" in the lower right corner.

Select material size from the dropdown menu

You will be prompted to select your material settings and place your material for each layer on your machine mat. I started by selecting "Light Cardstock" since I am using 65 lb cardstock for the colored pieces. Of course, if you choose to make this project with a different weight cardstock or maybe you want to add vinyl to your design, select the correct material for each mat. Additional material options are listed under "Browse All Materials."

TIP: If you are using different weights of cardstock, make sure to change your material setting for each mat for the best cut results.

Browse All Materials in Cricut Design Space for Valentine Mailbox Craft

Once you have your material selected, I recommend selecting "More Pressure” for the cleanest cut.

Select More Pressure for Valentine Mailbox Craft Cut Pressure

Since some of our mats have score lines, we need to add a scoring tool. I’m going to use my Scoring Stylus.

If you are using a Maker or Maker 3, Design Space may prompt you to use a Scoring Wheel. You can, of course, but you can also click "Edit Tools" and select the Scoring Stylus.

Valentine Mailbox Craft Edit Tools Selection for Stylus

I’m going with the Scoring Stylus because otherwise I will need to switch the Scoring Wheel in and out for every mat because the fine-point blade and the scoring wheel both go in Clamp B, while the Scoring Stylus goes into Clamp A. This way, there’s no need to switch the Scoring tool and blade in and out, which takes less time. And I’m all about saving time!

Place your cardstock on your mat. I recommend using your brayer to adhere your cardstock securely to the mat.

Use the brayer to best adhere the cardstock to the cutting mat

Load your mat into your machine and press “Go.”

Press go to cut design on Cricut for Valentine Mailbox Craft

When your machine is done cutting, unload your mat. Flip your mat over and gently peel it away from the cardstock. This helps prevent your cardstock from curling or ripping.

Sometimes pieces can be a little tricky and stay on the mat. Your scraper tool is a great help in removing any little bits from the mat.

Use a scraper to remove cardstock from the cutting mat

Prepare the next color of cardstock on a mat and repeat the steps until your whole project is cut.

Cut pieces laid out of for assembly of the Valentine Mailbox Craft


First, we're going to secure the body of the mailbox to the base. Gently fold the tabs of the base along the Score lines. You can use your scraper to help get a nice crease.

Fold the tabs of the base for the Valentine Mailbox Craft

Apply a thin line of glue along the outside of one of the long side tabs.

Apply craft glue to the base of the Valentine Mailbox Craft

Before gluing the body of the mailbox to the base, notice the small hole cutout, which marks where you will attach your flag. Flip the body of the mailbox until the flag hole is where you want it. Align the edge of the rectangular body piece to the sticky base tab and hold it in place. I held mine for about 10 seconds, but it may vary depending on the type and amount of glue you use.

Press and hold to adhere glue for the rectangular piece of the Valentine Mailbox Craft

Once the first side is attached, repeat the same steps to attach the other side to create the main part of your mailbox.

Once the main part of your mailbox is assembled, it's time to put the back on. Gently fold the tabs of one front or back piece along the Score lines.

Fold tabs of door on Valentine Mailbox Craft

NOTE: The front (door) and back pieces of the mailbox are exactly the same so it does not matter which one you use first.

Once all the tabs are folded, apply glue to two or three tabs at a time. Align one of the long rectangular trim pieces to the edge and press and hold it in place.

Apply glue to the tabs to apply the trim cardstock for the Valentine Mailbox Craft

Once the first few tabs are set, repeat the process along all of the tabs by gluing a few at a time.

Press and hold the trim to adhere to the back of the Valentine Mailbox Craft

Once your back piece is complete. it's time to attach it to your mailbox. Add glue along the tab on the base of the mailbox and along the inside of the curve of the back piece you just assembled.

Gently align the back to the mailbox and press it in place. You may find it helpful to reach through the inside of your mailbox to apply pressure from both sides.

Press inside of mailbox to back section for Valentine Mailbox Craft

Repeat the same steps to add a trim rectangle to the remaining front piece to create the door. Add glue just to the bottom tab on the base of the mailbox. Don't apply glue around the arch or the door will be stuck shut!

Apply glue to base tab for front door of valentine mailbox craft

Align your door and press it against the tab to adhere it together. You're almost done!

Fold the small rectangle piece along the Score line to make an L-shape. Apply glue to one outside surface and press the pull tab onto the door of your mailbox.

Choose a mini brad fastener to compliment your mailbox. Poke it through the hole in the bottom of the flag arm and then through the hole in the body of the mailbox. Open the brad inside the mailbox to secure it in place.

If you are making a basic mailbox, you're all done with the assembly. Feel free to decorate it however you like.


If you're making the unicorn, let's get those pieces added.

Let's start with the horn. Gently roll the horn piece into a cone shape.

Apply a thin line of glue on the inside of the horn's long edge and hold the cone together until the glue sets.

Use craft glue to glue edge of unicorn horn for Valentine Mailbox Craft.

Gently fold the horn base tabs outward so they are ready to glue on to your mailbox.

Next, let's roll some flowers using a paper quilling tool or my DIY Quilling Tool. Place the outside end of the paper rose into the quilling tool.

Start at the outer edge to roll paper flower with a quilling tool for the Valentine Mailbox Craft.

Begin rolling the paper flower around the quilling tool until you get to the end.

Pull the rolled paper rose off the quilling tool to remove it.

Add hot glue to the bottom of the rolled paper flower then fold the circle piece on top the hot glue.

TIP: To avoid burning any fingers, you can use hot glue finger protectors.

Press and hold the bottom of the paper flower with finger protection

Manipulate the petals by spreading them out. You can also use a small wooden dowel to curl the petals. I am using a 1/8" wooden dowel to curl my petals by rolling the petals around the wooden dowel.

Repeat these steps for the other two flowers and set them aside so we can prepare our unicorn ears.

Glue the inner parts of each ear to the outer ear. Fold the tabs forward to prepare them to glue to the inside of the door.

Press to adhere inner piece of unicorn ear to the back piece for the Valentine Mailbox Craft

We now have all of our unicorn pieces ready to attach to our mailbox.

Let's glue the horn first. Add a small dab of glue to the tabs of the horn. Gently place and hold the horn in the center top of the mailbox. I placed my horn about 2.5" from the front edge.

Attach unicorn horn to valentine mailbox craft

Next, let's add the flowers around the base of the horn. You can add them however you'd like. I'm going to place one in the middle front and the other two hugging the middle one on each side.

Attach rolled paper flowers to top of Valentine Mailbox Craft

Let's give our cute unicorn some ears. I have about 1.5" between my unicorn ears. Apply a small dab of glue to the ear tab and press it along the inside of your door trim so the pink will be visible once it's closed.

Glue and press unicorn ears to valentine mailbox craft

I recommend keeping your mailbox door open while the ears dry so that you don't accidentally glue the door closed.


I’ve also included a cute set of Valentine’s Day cards to use with the mailbox. There are seven different Print Then Cut designs to choose from. You can Upload one or all seven and print as many as you like! If you’d like to use them, here’s how:

In Design Space, on the left side of your screen, click the "Upload" icon and then click “Upload Image.”

Select uploaded file and add to canvas for Valentine Mailbox Craft

The card will now be on your Canvas.

Here, you can resize the card to any dimension you like in one of two ways. Use the resize handle on the lower right of the card's bounding box to make it smaller or larger by dragging the double arrows.

I prefer to enter the width ("W) I want under "Size" and the height ("H") will automagically adjust. Make sure to keep the padlock locked to maintain the proportions of the design.

I'm making my card 3" wide and I’m ready to print. If you want to add more cards to the Canvas and print them all at once, you can do that now, just repeat the steps above.

If you’d like to print multiples of this card, simply click on it and then click “Duplicate” as many times as you like.

Once you have all the cards ready to go, make sure you have the right machine selected at the top of the Canvas and click “Make It.”

NOTE: Print Then Cut Images can only be made on the Explore or Maker series cutting machines.

On the “Prepare” screen, there’s nothing to change so click “Continue.”

Now on the “Make” screen, it’s time to Print. Click “Send to Printer.”

Make sure you have 8.5" x 11" white cardstock in your printer if you want to make your cards heavier than normal printer paper.

The Printer setup window appears.

Make sure "Add Bleed" has a green slider. The bleed is a small border around each image that allows for more precise cutting. The bleed is trimmed off during the cutting process resulting in a precisely cut image.

You can continue by clicking "Print," however, I like to change the slider to green for "Use System Dialog" before I click "Print." 

Valentine Mailbox Craft choose system dialog for print then cut

This brings up a system dialog window for my printer, which allows me to specify the paper tray my printer will pull from as well as the quality of the print job.

NOTE: You will need to minimize or move your Design Space window to see the system dialog window as it pops up behind Design Space. There is a chance the system dialog box will not work on all printers. Each printer is different, so consult your printer's user guide for additional support.

In the system dialog box, I will select “Best” for print quality. Make sure your cardstock is loaded in your indicated printer tray and click “Print.”

Valentine Mailbox Craft print then cut select best quality to print

Once printed, make sure to let the ink dry to avoid any smears during the cutting process.

This is what my printed card sheet looks like. You will notice a black box around my cards. This is called a registration box and is used by your Cricut cutting machine to tell it exactly where to cut your project.

Now that we’ve printed our cards, click "Browse All Materials” to select our base material.

I’m using Medium Cardstock for my cards, but make sure to select the material you are using.

Questions About Valentine Mailbox Craft and Cards

A white Valentine Mailbox Craft made out of paper with red trim, flag, and heart decorations on a light teal background

What is a Valentine box?

The paper mailbox is a fun way to give Valentine gifts and decorate your home! Some people also bring a box like this to work or school around Valentine’s Day to receive cards they make for each other. I like to store favorite notes and small keepsakes in them to treasure throughout the year.

What is the best paper to use for this project?

We used 110 lb. cardstock to make the mailbox sturdier, but you can also do this with 65 lb. and 80 lb. cardstock!

How should I decorate my Valentine’s mail box?

However you like! Adding a name in marker is a quick custom decoration. You could also tape your favorite Valentines to the sides! Or go crazy like we did and cover it in hearts or paper flowers!

What should I put in my Valentines mail box?

Well, anything you want, really, but this Valentine mailbox craft is perfect for gifting and receiving cards or gifts! You can keep your favorites inside and revisit them for a little dose of love year round. Or, give a mailbox to a friend and sneak mail into it when you visit!

How do you make a Valentine mail box out of a shoebox?

If you don’t want to make a box in the mailbox shape or want a sturdier structure for moving around, just cut out the details and add them to a shoebox! The ears, horn, and flowers can easily be glued to the outer top and I would attach the eyes on a short end of the box itself. You can even still use the movable flag by adding your mini brad to the side of the box. Then keep decorating!
