To be honest, I use quill and paper to RP paintings themselves because, well, when the easel goes up, the description disappears (a DM and I tested this. :/). So I still had to have something to represent the painting, although it would be neat if it could be some sort of persistent placeable--my big worry with being a 'painter' PC is that people will have to carry the pieces of paper that represent the paintings everywhere they go, taking up space, and not really doing much other than being RP tools (which, admittedly, is just fine with me, but I'd like it if it were more useful to the people I'm selling these to!).
