I have a print that's 12" x 36" and I can't seem to find a frame to find it. Closest is 11 3/4" x 36" but that is, of course, too small. I don't want to mat it either. So far I've checked Michaels, Target, & Walmart...no luck. I'd rather not spend a bundle so custom framing is not really the way I want to go. Any ideas/stores?
