I am not gifted in the least bit artistically. I think I can manage stick figures pretty well, and that's about it. However, by following the illustrations in this book, I was able to come up with some credible designs. Enough that my free face-painting session at a bookfair was well received. I have to admit I gained some confidence in myself, too. The paints are adequate for up to 100 faces ... depending on what you choose to do. I kept my designs simple and small. I didn't attempt the fairy face, though it doesn't look too hard when you have step by step illustrations. The paints wash right off with warm water and soap leaving only the faintest of lines if you don't wash it off well enough. None of the children I practiced on had any allergic reactions to the paints, so I'd say they are mild. However, I did read on the instructions that you aren't suppose to use certain colors near the eyes. It would be interesting to find out why that is.  I also had to buy additional brushes, sponges, etc. because one brush/sponge wasn't adequate.
