Well, another fail in that I forgot to take pictures in the making of these little fellows!
I did take this one which shows I first spray painted them in white, then went over them in red. I obviously painted the faces on the white part, using a flesh tinted paint color for the face. Everything else is pretty much self explanatory, except for the hair. If you do decide to paint Santa's or anything else with hair, a must have is a "rake brush". For Santa, you base coat your beard and hair a grey color, then dilute white paint and slightly go over the grey with an almost white wash. The rake brush really gives the appearance of hair!
While I don't have any step by step instructions, I would add that if you want to add texture to the "fur" of a Santa hat, or add snow to an art object, Snow-Tex is an awesome and easy to use product!
