Guess what??? I was browsing through the frames section at Target yesterday, and came across a new line of frames they had called "Sprouts" for Scrapbooking -- 12x12" and 8x8" wood frames just for scrapbook layouts! I only saw them offered in a light colored wood (I was hoping for black) -- but hey, it's a start!
Might the mainstream framing industry be catching on to our need for square frames?
