A couple of years ago, I was rummaging through what I euphemistically call my Art Supply Closet - though in reality, I keep everything from actual art supplies to maps, to jars of fermented tofu to a waffle iron (just in case I ever need an emergency wedding shower gift) - when I found a tupperware container of what looked like cloth scraps. I put it out for my students - a group of 13 year-old girls, in this case - who were delighted to discover that it was full of Barbie Dolls and Barbie clothes.
Since then, my students have been able to use Barbie, Skipper and their friends in any number of dioramas and puppet shows.
A couple of days ago, I was shopping at one of the GoodWill stores near me. (Don't make that face; they have the BEST teacher clothes!), when I discovered a bin full of Barbies for 99 cents each.
I don't happen to need any at the moment, but if you're in Hooksett, New Hampshire by any chance, you should pick some up.
