There were not too many sources for 3-4 yards of BB Fabric. I got the flannel for the back from JandOfabrics.com. And the Lucky Lady BB Gambling material was from morningdove.com. The shipping time frame and cost was very quick and reasonable by morningdove, but J&O took 3 weeks and was twice the shipping charge.
No one locally had any BB material, and ebay is full of fat quarters, not yardage. So it took me a while....
