I got a tip off a website and this is what I do. She said unless you are having it judged in a show, do a small zigzag by machine. I sew it on the front, using 2 1/2 in binding, at 3/8", straight stitch, then I flip it over and fold my binding down on the stitching line I just made, and sew a very small zigzag with invisible thread hitting both sides of the binding with the stitch. I have really good luck with YLI in both my bobbin and top thread and my stitching doesn't show. I use regular cotton thread when I first sew it on my quilt from the top side, invisible only on the back side for my zigzag. I use the folded edge of my binding as my center for the zigzag stitching. It looks good, is fast and I love this way.
