You might have just solved the clue. I use the Guttermann I buy at Joannes and that is the only fabric store around our area, since Walmart does not sell fabric here, fabric stroes are few and far between, We used to have a Hancock Fabric store, but they closed down and never reopened on on this side of town so you have to drive 30 minutes to get to one of them. Even some of the quilt stores have closed and they are far & betwenalso., but now that fall/winter is coming, quilt shows are happening and fabric comes right along with it,but so does the prices of the material an we all know they mark that stuff up.
