A question for those of you exhibiting images that are square (either because you shoot MF 6cmx6cm or crop them square) - have you found a good source for frames and mats? I'm looking in local stores, on the 'net, not having much luck. I'd like to find frames (and mats) in the range of 12"x12" (for an 8"x8" image) and 16"x16" (for a 10"x10", or 11"x11" or 12"x12" image).
