Thanks for the information everyone.
Ice Blossom, I laughed when I ready your "tiny vine-y" comment as the particular fabric I recently bought can be described exactly this way. When I come across 4 or more yards at the thrift store I usually buy it for backing fabric, figuring it will eventually match some quilt I make. This one was a super light teal-ish green with small pink tulips. After I bought it I kind of regretted it because it looked so dated, but lo and behold I found a match for it. The BOM I participated in this year at my LQS was a super scrappy, one block quilt so nothing fancy. Something about that old Joan Kessler fabric was a good match.
