Panther,
Can I see a picture of your bags?
Glue is a great idea. I have been working with the idea that one should try to use one piece of string, if at all possible. The more pieces, the more doubled stitches show up. However, I can see how your method would really help out this bag construction. Honestly, I hadn't even considered a better way to sew it together, especially one that meant beginning and ending several times. Thanks!
Tomstas, you're not kidding. Watch bands, for instance. I haven't tried one because I haven't got the tools, but before the last six months, I wouldn't have known I needed other tools. That, for me, is progress.
