Use equal parts water and flour to make this. I used 2 cups each. Mix well and then add food coloring. I poured mine into baby food jars and then added the food coloring in order to have a variety.
I like that I don't have to worry if the toddler gets this in his mouth. Yesterday was day two of using this paint. I would suggest that you shake it really well after it sits for a while. The flour starts to settle to the bottom.
I hope you are taking time to enjoy the simple moments!
