I use mine to make chemo caps that look like biker caps. I use wooly nylon, as it is softer on the bald head. I also use it for edging items I don't want to bind. I have seen on some quilting show that someone used their serger with the knife down or so that it doesn't cut, to put decorative stitches on crazy quilts. I wish that I could remember the show. Maybe Kay Wood? Sorry it posted twice.
