Halloween is right around the corner, which means it’s time to carve pumpkins and pick out a great costume. It can be a hassle to choose a costume and decorations that are good for the environment, let alone create one from scratch, but have no fear: we found a few cool ideas to make your Halloween costume preparation easy and friendly on the planet. Check out six ways to have a spooky and sustainable Halloween.

1. Make your own face and body paint.

The Hulk. A witch. Garfield. The good news for costumes like these that require paint: it’s super-easy to create color that’s safe for your face and body. Most body paint recipes call for ingredients that are likely already in the pantry, fridge, or bathroom cabinet. A simple body paint recipe is just cornstarch, body lotion, water and food coloring. Check out Chelsea Lee Gilbert’s Halloween-tested recipe on Instructables for an easy recipe. Or, if you really want to step up the cosplay this Halloween, check out Brit (of Kait and Brit)’s awesome DIY video on YouTube.

2. Go as an eco-friendly character.

If you or your kiddo are one of the many young advocates fighting against climate change, go the extra mile by dressing up as one of these homemade eco-themed costumes like Vampire Energy, Captain Planet, and the Lorax. If the effects of climate change aren’t enough to give your community a fright, these costumes will.

3. Invest in a onesie.

If costume creation isn’t your style, buy an outfit that’ll work for Halloween and kicking it at home all-year round. Personally, we love these cute koala pajamas from Amazon, this sloth jumpsuit from Target, and this colorful SpongeBob Squarepants Patrick Union suit from Hot Topic.

4. Upcycle kids’ old costumes.

Upcycling is simply repurposing old stuff into new stuff so it doesn’t go to a landfill. Try using these ordinary household objects to make kids’ costumes like a toy soldier and an ace of hearts. One classic Halloween upcyling idea: turn a sweatshirt and sweatpants into a skeleton costume. And don’t forget, an old pillow case makes a great trick-or-treat bag. Why not trick it out with homemade paint or leftover ribbons to make your candy bag stand out?

5. Put your pumpkins to good use.

Pumpkins are good for more than just scary jack-o-lanterns, so keep and roast their seeds for a great snack after the holiday. Want to go the extra mile? Host a pumpkin composting party for your friends and neighbors!

6. Decorate your home with reusable Halloween decals.

Etsy sells eco-friendly, reusable Halloween decals like bats, gothic birdcages, and eerie ravens. We love this spooky Harvest Moon decal!
