In the past, I've made most of the boys' costumes but now that they're older they only want the store bought ones. For the past several years, William has been a Ninja of some kind. (The picture above was last years' Ninja) This year....Ninja again.
I think my favorite costume as a kid (despite the layers of wool) was the "I Dream of Jeannie" year. Definitely a fave. My favorite costume for the boys was the Parrot, The Train or The Spider (that's Jack pictured above in the Spider costume). I think I had as much fun making them as the boys did wearing them.
