If you are an artist, buying many frames, you may like this tip. Ask your favorite framer to make you standard size frames from his "end pieces" of moldings. Often these are thrown away and my framer is happy to have a chance to use them. As a result, he sells them very inexpensively, attracting more business from artists. A win, win situation.
