When we purchase fabric from a Quilt Shop, we think we are getting top quality fabric. May not be so. I purshased some Clothworks brand fabric for $9.95 yard. As I started working on a new pattern Tribble Trouble, the trouble really began. I could not made the blocks come out to the right size. Finally I figured it out. A 8 1/2 inch block was shrinking by 1/2 inch when I applied steam. The width of the fabric was shrinking. I called the quilt shop and they ask me to bring it in. They did replace the fabric with a new piece that I washed and dried this time, but they did not want to replace. Only after I insisted, did they replace. So if you do not wash first at least steam and dampen heavily.
