I also buy the big roll from JoAnn's. A friend pointed out the savings and I ran the numbers. I make lap size quilts. When they go on sale for 50% and free shipping, I purchase. (When I'm low). It amounts to less than $7.00 a quilt for a 48x72 size. Since I don't plan on stopping anytime soon, that's savings. The hardest part was deciding what to purchase. I tried several battings before I decided which one I wanted in quantity.
