I repeatedly say that for dense art quilting.... I work from the center of the quilt, methodically moving upward , outward, downward. NEVER has that been more important working on this very wide door so heavily quilted. The right side of this upside down quilt really had a serious 'wrinkle in the rug' thing going on. The top looked like it had stretched a bit (more likely I hadn't pinned effectively), and the batting was thus buckled inside, though the backing was just fine. Look above at 'the big lump'!!! So some unpinning, repositioning was paramount. Now to reposition the outer edges as well and we're ready to finish the door quilting.
