i once saw a woman on a craft show use tow slices of white bread (no crusts), in a zip loc, add two tablespoons of white glue and mush it all up. when the bread had full absorbed the glue, the bread feels drier to the touch. you roll it, and play with it till it's play doh. u can add food coloring to make it different colors. then she used it just like regular air dry-clay. we used that for crafts once and it worked great. we made minitaure roses and laqured them. they look just like clay made ones. when i was a kid i mushed up white bread into a ball all the time. when i told a friend about the clay, and then she recalled how she also used to "play with her white bread," because it's so doughy, she said she could no longer give her kids white. she would think of this big lump of dough they had to digest.
