Play dough Christmas trees

This is my favorite play dough recipe.  The texture is so smooth.  

1 cup white flour

1/4 cup salt

2 tsp food coloring

1Tbsp vegetable oil

2 Tbsp cream of tarter

1 cup water

Mix flour, salt, and cream of tarter in a medium pot.  Add water, food coloring, and oil.  Stir over medium heat for 3-5 minutes.  Don't worry if the mixture looks like a globby mess; it'll turn into dough.  When the mixture forms a ball in the center of the pot, turn off the stove and let it cool.  Then take it out of the pot and put it on a floured surface.  Knead it.  Store in a plastic bag in the fridge. 

This is Fluttershy's Christmas tree. 

Use green play dough with colored beads or marbles. Children can use the green play dough to make Christmas trees and add the beads or marbles for ornaments.
