I remember, way back when I was just a kid, my great grandmother had quilt frames supspended from the ceiling. The frames were made out of just plain old lumber (2 X stock). When the quilters wanted to quilt, the frames would be lowered to the right height for quilting. I don't remember too much about the construction, or how the quilt was fixed in the frame, or anything. I just know it was really strange to see one of those frames hanging from the ceiling!
