(not a very good pic, but you get the idea!)
This is just salt dough, so pretty simple:
1 c salt
1 c flour
1/2 c warm water
glass marbles
Preheat oven to 200 F. Mix all together. If you want to make a colored stone, add your desired food coloring (Elijah wanted purple) and form a ball. Line a pie pan with parchment paper. As thin as you can get it, roll the dough out in the pan. Gently push the marbles in the dough in whatever pattern you want. Bake in preheated oven 3 hours. When you remove it, if it still seems wet or doughy, flip it over and bake another hour.
Fun and super easy to do! We'll definitely be making more, if I ever make it to the store to get more salt! :)
