I saw this idea on Pinterest so here is our take...
1 pack of sharpie markers mini from Joanns which were $12
2 plates from the dollar store and 2 mugs that are microwave safe
1 2 year old
2 1 year olds
Wash the plates and mugs, remove stickers on the bottom
Let them color but not eat the markers
Bake at 350* for 30 minutes
