Thanks, Carol, that's very true.. But like I said before, that some people like standard size paintings that are much easier to find frames for. I know that you can't please everyone, but I think if I was a buyer, I would opt for 5 x 7's for framing purposes.
Wait a minute....After thinking about this more, if I was a collector, I would buy a painting that speaks to me even if the format isn't what I want. If I want it bad enough, I would find a frame for it. After all, your not searching for art to buy because of the frame.
Anyway, I already toned all my 6 x 6's with earth colors and they're ready to paint on so I'll just work with them.
