Looking for something else to do with rubber stamps?

Oh you can certainly use them with polymer clay and embossing powder, but have you considered the vocabulary building aspect?“F’ower Mamma?”

“F’ower?”

“See f’ower Mamma?”

Then there is the block aspect of wood block mounted rubber stamps.  You can stack them, put them in a box,

Knock them down, spill them out of a box.

But I don’t recommend EATING them!
