LAers, Pieced Backings
I just finished a quilt with a pieced backing. The center of the backing was a large piece and 2 different strips were attached to each side. The backing was not squared, so the customer said that I should just do the best I could. When I rolled the backing on the belly pole it veered to the right and since I float the top as much as I wanted to keep it centered it would not yield. So when I finished the backing was a little angled and the attached strips were very angled.
My question?? how do you center pieced backings when they are pieced vertically? Should I have refused to quilt it if it was not squared? Maybe I should have pinned it horizontally?
