I do have a Joann Fabrics near me and buy when fabric is on sale but even their sale prices are getting expensive.
I like to look at the Connecting Threads fabrics, in their clearance section. Not all of their fabrics appeal to me but some do, especially the batiks and the prices can't be beat. Even if the fabrics don't appeal to me for the top of a quilt, I'll use any of the clearance fabrics for quilt backs.
