That is awesome! The Green Army Men were one of my favorite things in Disneyland/World.
I don't know what I'm gonna be...I really want to be the Queen of Hearts from Alice in Wonderland, but I hate buying costumes and I want the full elaborate costume, and I just don't have the time/money/skills to make it.
Ditto for Harley Quinn from Batman...I desperately want to do it, but a custom-made costume is $300, and I can't make it myself. Time to invest in a sewing class, maybe?
