Start stockpiling your recycling. Once your kids start making these they won't want to stop. For the best results you want #6 plastic (look for the number stamped in the triangle on the bottom of your containers). I found that 6 is hard to find, but I had tons of #1 plastic so I tried it with both. The 6 definitely worked better, but they both worked. The #1 didn't flatten out as well, but it did shrink, so experiment with #1 if that's all you have (The large heart in my photos was made with #1).

1. Let kids draw their designs on paper first. Then trace them onto the plastic and color them in with Sharpies.

2. Cut the designs out holding them by the edge so you don't rub the marker off. If you want to make charms, use a hole punch to make a hole. Use your scraps to make more designs. Place designs on a lined cookie sheet. 

3. Bake in a preheated 350 degree oven for 2-3 minutes. Watching them bake is half the fun, so keep an eye on them as they curl up and then flatten out again. When they have mostly flattened, they are done. If they don't flatten out perfectly, use a spatula or similar to press them flat. You can also pop them back in the oven to warm them up again and flatten them out more if needed. 

Show us what you make. Share it on Facebook, Twitter or Instagram and tag @mommypoppins so we can see your creations too!

NOTE: Heating plastic can release toxic fumes. We did not notice any fumes with the very small amount of material in this project, but try this craft only in a well ventilated area and at your own risk.
