library

I have been asked by a friend to help put together a beginning bread baking class at the local library.  We can not actually bake, and can't let participants eat anything I bake ahead.  This will essentially be a lecture.  I would love advice on how to provide the best experience for all.  

I am thinking that I may bring some dough to allow participants to feel the dough, watch shaping of a loaf.  Any and all input is appreciated.
