Recently my daughter got a book for her 5th birthday called Ed Emberly's Complete Funprint Drawing Book. She loves it. If you have never seen this book, it shows how to make little drawings with a fingerprint. It is very cute.
I figured since there is a good chance that my daughter actually uses ArtRage more than I do I would try to make a sticker for her. I don't have somewhere to host a sticker sheet file so here are the images I used and a couple of examples of art that can be made from it. I won't go into how to make a sticker since I mostly bumbled around until I got it right. There are some good tutorials in the forums though.
