Yesterday I read you can make non-toxic finger paint by mixing Kool-Aid with plain yogurt.
Me, I never finger-painted much as a kid. Too messy, I think. I used crayons since they came in like a zillion colors and were widely available but I never cared for the waxy texture. I liked markers the most.
Anyway, I guess it's up to what the kid personally prefers most, especially if they may actually be a future artist, which is what people said about me. Can't stifle their creativity! I now generally use permanent markers since they're bright and bold and don't fade as much as water-based markers, but I don't use them too often since I'm not really fond of coloring.
