We use homemade play dough too because my toddler is always trying to eat it.
Homemade play dough rocks my kids world. I'm a fan too. We make it regularly.
can you bake this? or do you just let it air dry before painting? does it store well?
You probably could bake it. I had added food coloring to it. We put it in a plastic container and it seems to be doing well. The salt should help to preserve it. I would say it is similar to PlayDoh.
