"I just received a couple of quilts that were stitched around the raw edges. What a nice touch! Fabrics do stretch, particularly if there are bias edges!"
I always stitch around my quilt top before I give it to the longarm quilter, as well as trimming threads, squaring up and pressing it the best I can. I also give her oversized batting and backing. She's never said anything about my quilts but next time I'm going to ask her if there is anything I need to do before I give her a quilt.
I donate a lot of quilt tops to charity groups to finish and I always stitch around the top to keep seams from opening and also attach binding to go with the quilt.
