Martha Stewart's website has a ton of great ideas for costumes.
- I first saw these 6 Hair-Raising Ideas in the Marta Stewart Kids magazine that sadly doesn't exist anymore. My two favorites are the Rose Garden and the Ice. I think they might have a real chance with my kids in a couple of years when they're past the regular "dress-up" phase.
- She also has some cool family costumes. My picks are the Outer Space and Woodland Creatures (instructions here).
- And how sweet and easy is this Leaf Garland Costume ?
