Nope. I've quilted probably 800 - 900 customer quilts, and have never had one with a serged edge. Very occasionally I've had a top where the seams at the edges were coming undone, but that only seems to happen if the piecer used too long of a stitch length or handled the quilt very roughly. I also am careful not to overly tension the quilt top, so I haven't had problems on most quilts.
