I did not use a pattern. I cut 2 18x20 sheet that I had and never used. and then layered tons of small scraps from my bucket...2 1/2 and less - about 6 layers, then laid a white left over piece on top and then the other 18x20 piece of sheet oh and also left over batting on top of the first sheet - then I quilted lines up/down - left to right...then I cut the squares up and also a few layer under it...threw it in the wash and then made a bag.
