I have some advice on the best face painting supplies to get.
I have used different face paints but the best one I have found was Wolfe face paints.
They are not thick and dry easily but it has a lot of pigment in them.
But the only place that you can get them is online or at least that is what I have found.
This store online has all the Wolfe paints and palettes and I recommend getting a palette if you are just starting off with face painting. The palette will give a taste of all the paints and it will last a while too.
