I didn't stitch around the edge on a recent baby quilt I finished and really regretted it. It was a pieced quilt and I wound up having to "unsew" part of the binding to go back and make sure the pieced sections didn't pull away from the binding. I did extend
the batt into the binding because I like that look on a baby quilt,
so that may have had something to do with it,because I usually don't have that problem on a pieced quilt. Next time I will sew around the perimeter first for sure!
