I've been making a bunch of pillow cases for my grandkids and also for a Craft Show. I have never figured out how to finish off the end of a serged seam. I gotta do something or it will unraffle, but what? I have been going in with needle and thread and sew a few stitches to seal it. Not to mention I just broke my sewing machine needle trying to do it by sewing machine.
Is there a better way?
