My little Scarlet has a "getting into mommy's makeup" problem thats been going on for months. When I came across this idea I had to try it, despite the fact that it isn't at all natural. I found the tutorial here
It's basically old makeup containers filled with different colors of nail polish.
Let it dry and then voila! you have pretend makeup that's fun and looks super real.
I had three busy helpers so mine aren't perfect but I think Scarlet will be in heaven. We bought some little brushes and a mirror compact and some fancy bobby pins from the dollar store to go with it.
