I bought a bolt- 40 yards x 90" wide Warm N Natural from Joann's at 50% off before Christmas. it costs about $2.00 a yard less. Felt guilty not getting it from lqs, but it's a substantial savings when you are serious about your quilting obsession.
I like having it handy, I can see exactly how much is left. I always seemed to need batting even though I would buy enough for 2 or 3 quilts at a time.
