Joseph Had A Little Overcoat by Simms Taback is the current favorite. The ladies enjoyed cutting and pasting magazine pieces onto their own traced overcoats as a follow-up fancy.

It's fun to break down the colors and collage pieces and seek "similars" in a magazine.
We made a story-telling board collage with faces from magazines as inspired by this page.
The girls picked the faces and "characters" and we created a base for inventing our own stories about the inhabitants of "Overcoat Park". I hope we get to use this as a means of creative conflict resolution by telling stories which create empathy for one another when there is a "fight" or intractable squabble.
