My children have happily been playing with this naturally-dyed sensory playdough for weeks reminding me that simplicity is often the key to success even with children.
In a medium-sized mixing bowl, add flour, salt, cream of tartar, and pumpkin pie spice.
Heat 1 cup of water. Add the water to flour mixture. Now, mix! Mix, mix, mix.
Once the dough is firm enough to handle, scoop the dough with your hands and knead until you have a firm playdough.
Divide into three small balls and add the food coloring of choice. Knead the dye into the dough, adding more dye to achieve the color desired.
During play time provide extra pumpkin pie spice or fall spices in small bowls (cinnamon, allspice, ground cloves) for children to sprinkle on their dough and experience fall.
