I didn't post this enabling link in this thread before, but if you are still hankering after some 118" wide, the eQuilter backing sale has been extended to Wednesday. Only a few 118, most are 108, but there are some. Deal is 25% off, free postage after $100 (which isn't hard to do with a couple of backs). Solids and flannels are not included.
