I originally published this tutorial over at Crafting a Green World.
These 3D paper hearts are the perfect decoration for a perfect day!
My favorite projects are the ones that I can make with the supplies that I already have entirely on-hand… and my second-favorite projects are the ones that I can easily recycle, upcycle, compost, or otherwise entirely dispose of with little effort if I decide I no longer want them. Because although I love decorating for a holiday, I think I like taking down all those decorations afterwards and enjoying my (relatively) clutter-free home even more!
This cute 3D paper heart project encompasses both of my favorite things! Use any of your favorite papers (in these photos, I’m using vintage book pages) to craft these pretty paper hearts, and after Valentine’s Day, pop them into your paper recycling, upcycle them as greeting card or scrapbook embellishments, or shred them and mix them into your compost. Just between us, I don’t even shred them first, because I am a VERY lazy lasagna gardener.
Or keep them on display forever, because they’re just that cute!
Materials
To make these 3D paper hearts, you will need the following supplies:
- pretty papers. You need enough paper for 8-12 hearts, depending on how full you want your finished 3D heart to look. I’m using pages from a vintage book, but scrapbook paper would also be SOOO pretty. With larger hearts, the paper tends to curl if it’s very thin, so avoid lightweight papers like newspaper or wrapping paper for bigger hearts, or place thicker paper between the glued sheets to strengthen them. Cardstock would be perfect for a very large version, or even thin cardboard food packaging for a supersized version!
- heart template. You can freehand this or print out your favorite clip art, but since you’ll be making several identical cut-outs per finished 3D heart, you’ll want something to trace.
- tracing and cutting tools. A pencil and some scissors, or whatever you’ve got on hand!
- glue of your choice. A glue stick is my favorite glue for working with paper, but with all that plastic it’s not very eco-friendly, is it? SIGH! Fortunately, nearly any glue works well here. PVA glue takes a while to dry and you have to be vigilant to avoid curling, but it’s got much less plastic packaging than glue sticks do. Hot glue is in between, eco-wise, but it also dries nearly instantly and won’t cause curling.
Step 1: Cut out the paper hearts.
For the project in these photos, I’m using an 8″ wide template for the larger heart, and a 3″ wide template for the smaller one.

Trace and cut the number of paper hearts that you’ll want for your 3D version. The more hearts you use, the fuller your 3D heart will look. And the bigger your heart, the more hearts you’ll need to fill it out! For my smaller version, I used eight cut-outs and I think the end result is perfect. For my larger version, I used 12 cut-outs and I think I could have gone with at least 16 to have it look a little more full.
Step 2: Fold all the cut-outs in half.
If your cut-out is double-sided, take some time to choose which side you want to be visible in the finished product, and fold that side to the inside. The outside sides are what you’ll glue, and you won’t see them when you’re done.
Try to be as precise as you can with your folding, putting it right down the center of each cut-out, and crease the center fold well.
Step 3: Glue all the cut-outs together.
Here’s another place where you want to be so very precise!
Spread glue across one folded side of a cut-out, then stack the next cut-out exactly on top of it, pressing down to make sure that the two papers are adhered all over.
Spread glue across the folded side of the cut-out that’s now at the top of your stack, and stack the next cut-out exactly on top of that one, again pressing and smoothing to make sure the papers are well adhered.
Repeat until every cut-out is stacked and glued.
Step 4: Fluff out the finished product so the papers look nice.
Page through the whole stack of cut-outs and make sure that no glue bled through or seeped between the edges of the paper, and that none of the pages that aren’t glued are stuck together.

If you want to make your finished 3D heart into an ornament, you can insert a twine loop between the last two pages, then glue them together to seal it in. I, however, really like these opened up as a wall decoration, or, for the smaller hearts, glued to the front of a handmade valentine.
I kind of want to make a REALLY big one to put on my front door!
