While those orange plastic pumpkin buckets are cute, they're less cute when you realize how much petroleum goes into their production and how many get tossed in a landfill. Give your trick-or-treaters the eco-tools they need by making reusable Halloween bags. You can make one from an old pillowcase, scraps of fabric, old clothes or towels, used paper bags, or other found items around the house. Alternatively, buy some bamboo, organic cotton or hemp fabric and sew up two sides. Get creative with the decorations as well. By using washable markers, you can actually sleep on that pillowcase again!
