Roses are red, violets are blue... wouldn’t a homemade card be the best way to say “I Love You?” We’ve shown you how to turn your adult coloring pages into cards before, but this DIY is even better: Instead of creating plain ol’ cards, we’re adding 3D details for even more interesting designs! All you need is a few coloring pages (maybe one of our valentine’s day coloring pages or flower coloring pages?), scissors, and hot glue:

What you need:

  • Cardstock (you choose the color)
  • Colored designs (make color copies if you don’t want to cut up the original!)
  • Scissors
  • X-Acto, ruler, & mat (or paper cutter)
  • Hot glue
  • Markers (optional)


What to do:

Folding Cardstock in Half

1. Start by folding your base cardstock in half. Use your fingers or the back of a butter knife to smooth the folded edge.

2. Trim your folded cardstock to size. We cut this one down to 5x7-inches, which will fit perfectly into a size A7 envelope.

3. Now cut out your coloring page elements for the front of the card. You can really use whatever designs and whatever shapes you want—be creative!  Cut out hearts from coloring page

4. To get your shapes to stand out from the front of the card, you need to fold ‘em. For something like hearts or stars, you just need to fold them in half once. For something like a circle (think around a sun or flower design), you’ll want to fold it twice to create a “+” through the middle of the circle for extra texture. Note: If you are using a design that needs to face a certain way, be cognizant of where you’re folding the design! (For example, here, we had to make sure to fold the paper correctly so that the face on the design was in the right spot on the finished heart.)

Wait! Before moving on to step five, go plug in your hot glue gun and let it warm up (you’ll need it for step seven.)

5. Now cut out your shapes. You can really do whatever shape you want. We went with hearts, because Valentine’s Day! Cut out as many or as few as you want.

6. This step is optional: If you want to add any drawings or written details to the front of the card, do it now before you add your cutouts to the card. It will be much easier to color or draw on the card now than after you add the designs!

7. Use a small dot of hot glue to attach each cutout to the front of your card. To do so, add a small dot of hot glue to the card. Then, insert the cutout — FOLDED — into the glue, and use your finger to adjust the open-ness of the fold. It’s totally up to you: You can make them fairly wide open (especially if you want to put the card in an envelope) or make them more 3D. Let dry.


If you want to mail your work of art, the finished product should fit just fine in a padded envelope or small box. If your recipient is more local, these cards are even more perfect for presenting envelope-free alongside a vase of flowers or atop a box of candy.
