I had some left over 4 1/2 inch squares and just decided to make a scrappy with them as they were. I ended up liking the results. Sort of primitive, compared to the others here, but I liked it. Let me see if I can find a picture. Okay, this is before I got it quilted, but I just used SID and was very happy with it. Maybe this will give you an idea of what you might want to do. Obviously, it was easy.
Oh wait, I have another scrappy too, sort of a controlled scrappy. Let me see if I can find it. I made it after I got a "grab bag" of 2 1/2 strips from our guild and the challenge was to make a quilt.
