Thanks for the advice about the seams/stitch in the ditch. I understand what you mean. I was using Minky as a backing on the quilt top..the beautiful stuff with RIDGES. Well, it fights the machine even with a walk. foot. Person in the quilt shop explained this to me....NOW she tells me after I spent a lot of $ on another sale person's recommendation. Watch out for Minky...beautiful, but a fighter!
