Nobody is buying, that's partly why I asked the question. Not that my frames are necessarily the reason for my sales record, it could be the junk I put in them.
Anywho, today I went to the art institute, Michaels and Target. I looked closely at all the frames on all the art, something I've never done. One photographer used thin, silvery aluminum that I don't think I'd use but they looked OK. On close examination the corners weren't very well machine-matched but few people would notice it. Another photographer had a large exhibit of B&W prints in large, medium-width (1") black wood frames with an occasional white one. I have to say the white doesn't do much for me. The frames looked nice, well made, perfectly cornered, clean and unremarkable. They didn't ooze "expensive", and since he was showing dozens of large prints he'd have to be wealthy in order to afford that many expensive frames so they probably weren't. They were not a distraction, they were functional. I liked that width.
On to Target and Michaels, this part will be short. Even the most expensive frames they had on display looked cheap, and almost all looked like plastic or some plasticky susbstance. I didn't see if the frame shop offered anything better.
