DIY Halloween Costumes
17 Low-Plastic Ideas

I love a good Halloween costume, but here is the part nobody mentions at the store. When researchers checked, 83% of the material in those rack costumes was oil-based plastic, mostly polyester that sheds microfibers and ends up in the trash by November.

So here are 17 costume ideas you can make from cardboard, thrifted clothes, and things you already have at home.

These are the kinds of costumes your kid can help build instead of just wearing. They pick the one they want, tell you how it should look, and dig through the closet with you for the pieces. Pick one from the list, make it this weekend, and have some fun with your kids.
