I don't know the official name of this paper so I will call it puffy paper...it comes in thin sheets of 8.5 X 11 paper that you can run through the die cutting machine.....cut out lots of great shapes and letters etc and then when you place them in water, they 'puff up' into foam shapes for sponge painting :)
The Resource centre at Parentlink has endless die's to use to make shapes...seasonal ones too.....in fact they have endless resources for Moms or daycare workers or teachers etc.....very cheap too!
These foam shapes are also great in the bath tub - if you wet them they cling to the tiles or sides of the bath....
