My first FMQ bed runner, I overstretched the top, in relation to the back (first time FMQ'ing and with using the Frame! DUH!) and had one really massive "flap" of fabric. SO, I took the plunge, and actually folded the flap across the entire width and "stitched" it down. When I quilted over it, it wasn't visible. I washed it, then showed it to co-workers, several of whom are very accomplished quilters and NO ONE even noticed. I did piece the back, so maybe everyone thought it was a seam and not a boo-boo! Keeps us humble, doesn't it?!
