I'm beginning to get comfortable enough with oil to play around with it. (Apparently I'm still intimidated by it, it's been five years now.) I painted a light coat of the color I wanted for the wings and then wiped it off with a paper towel and what was left was a nice transparent feel. I also took the liberty of giving them all a bit more fur so they'd chub up and look fuzzy and, well, more cute. Ouch! Perhaps I meant more delightful...fetching?
