We made paint in a bag last week and it was super fun. I got two recipes for making your own paints from Family Fun crafts here and a different recipe to try another time here These recipes would also be great to try as finger paints. I loved this recipe because the colors aren't so transparent, and you can make it yourself without having to buy expensive paints from the store. We mixed up some primary colors and Otto smooshed them with his tummy and hands to see what colors they would "turn into". This was really fun, and the bags are still here and paint is still soft, almost a week later. The only thing I'd do differently is put the paints in bigger ziploc bags or put less paints in the smaller bags. Because if I'd have done that, we could use these not only to squish the paint, but to continue to do mess-free paintings like here. I think I'll transfer some paint over so some bigger bags this week to do some paint writing like that.
