29. I’ve been painting for about four or five years, about three professionally - which is to say I’ve been able to rely on it for income for that long.
The best advice I could give would be to start cheap with canvas and paints - any artist grade paint will do the trick. As far as brushes go, they don’t have to be anything fancy, but those multi-packs are usually crap. I like buying brushes in person as opposed to online, so I can feel the tension and response in my hands.
