my kids got into face painting after their grandmother gave them a book that details how to dress up as different characters.  grandma gave us some face paint crayons that were very difficult to work with.  I ordered this kit and have been so impressed with it.  I am not an artist, but when I follow the instructions in this book it looks like I am!  I've been able to create beautiful face paint and "tattoos" on my children and the children I babysit.  This would be great as a DYI for a birthday party!  No need to hire anyone, just practice a few times before the party, or even if you don't practice the kids will love it and think it's really cool!
