When thinking about the waste we humans create, think about Halloween: all those synthetic costumes used once, never again worn, come November 1st tossed on the trashheap of over-indulgence. And they’re often not designed with as much panache as you yourself could put in them.

It’s time for Halloween to go green. And so much cheaper, and more fun, too, to make your own costume—whether it’s a simple white sheet with eye holes cut out, or a papier mache mask, or a kitty-cat suit using your own yoga clothes. Get the kids involved in making their own costumes, and let them compete to see who can make the greenest! And it’s even more fun as Inhabitat is having a contest for green Halloween costumes, which you can enter here:

If you enter, send in a photo of yourself to us, and we’ll post it here, too.

By the way, Inhabitat is definitely worth checking out whether you’re busy making a green costume or not. It’s a site devoted to the dovetailing of great design and sustainability, started by New York City designer Jill Fehrenbacher. They have really cool news about really cool designs help save the planet, like this rocking chair.
