I found a recipe online for salt dough. It's 1/2 cup of water. 1/2 of salt. and 1 cup of flour. you just kneed it together. Add more flour if needed. Then roll it out. You can add food coloring if you want. Then make the impression and put it in the oven at 200° for four hours. They came out great! Made some of my daughter.
awesome gotta try this for my baby boy in a few weeks
