My two favorite painting crafts are stained glass and clay moldings.
Stained glass is elegant and easy to do.
It can be found in the craft and hobby section of almost any department store. It is inexpensive and lots of fun. You can find packages of paints and stained glass ornaments or buy them separately. The paint sets come in all assorted mixtures. Whatever paint set you buy, make sure it is a transparent type of paint because when working with stained glass you want to be able to see through the colored glass fairly well.
