as I read that some of you who have had problems with the stitches fraying on bags from the expandable lines. Can I see some pics of those fraying stitches and get an idea how does it look like? Does anyone not have a problem with the stitches? I saw the red expandable tote pic posted by roey and love how it looks on the pic! But I kinda worrying about the stitches after reading some TPFers with that problem. Any thoughts?
