I used to use templates cut from the plastic lids of cottage cheese or margarine containers. The corners didn't round off after drawing around it 100s of times. Then cut out with scissors, get blisters on my thumb from the scissors and hand piece together. I even did one by hand out of double knit, 2.5 inch scrap squares, hand quilted with poly batting. I still have it and it's still useable. I still have a tub of double knit, but I have doubts that I will ever use it.
