I'm on a big "homemade" art supply kick right now, so I decided to give finger paints a try. We usually just use whatever paint we have handy for finger paints rather than buying actual paint labeled "finger paint".
These paints turned out a little thick the first time, but with a little more water, they were great and super colorful. I think I used waaaay more of the gel food coloring than I needed, but oh well. They were a hit!
Start by mixing together 3 TBSP sugar, 1/2 tsp salt, 1/2 cornstarch and about 2 1/4 - 2 1/2 cups of water in a medium sized pot. After it's well mixed, put over med-low heat and let it "cook" for a few minutes until it starts to thicken slightly. If it seems way too thick, add a little more water, and stir.
Divide the mixture into your containers and then stir in a few drops of your food coloring. (Side note....if you are using gel food coloring, you only need a teeny-tiny bit...)
Once they paints have cooled, it's time to paint your heart out. (In the picture above, you can kinda tell how the first batch was a little thicker and clumpier than it should be).
This is our second batch...much smoother and much better!!
