I can sure relate to making mistakes - last weekend I was working on a project for my online class - a little zippered bag. Had trouble with the serger and realized that I had not cut off the end of the zipper just as it got to the blades. So I stopped sewing, cut the end of the zipper off, continued to sew. That end stitched out just beautifully. Got ready to stitch the other end and started to cut off the excess zipper. That's when I noticed that I had cut off the zipper pull on the other end. Oh well! You know what they say - "STUFF happens!"
