Sometimes someone pays to to paint something.

I just spent an enjoyable half hour talking to the buyer in the parking lot at my work (because art deals, like drug deals, should go down in a parking lot. In cash). She said she was a patron of my art; I told her she was The Patron of my art, as far as I could tell -- other people have bought my work, but the only other people with more than one painting are my aunt'n'uncle (commissioned nursery art, again) and my parents (who're storing the stuff that's too big).
Really, I've been very lucky. Not only did a gallery downtown agree to show my Sheep in Space a few years ago, the one person who totally fell in love with them happened to visit the gallery at the right time and happened to be married to an orthodontist (orthodontists make bank). She bought about half the work I had up, then commissioned me to do a painting for her then-on-the-way first kid's room (a black sheep, white sheep, and little gray -- well, violet -- baby, to match their family). This is the second commission, for kid number 2, in which she stretched my artistic limits by asking me to paint them on the ground.
They don't even have helmets. It is not the natural order of things.
