[quote=Cordelia]I like to press open. BUT, no matter how many times I backstitch at the end, there's no doubt, the open seam is not as strong. I'm always having unraveling. I back stitch religiously to make sure that won't happen and can never understand why it happens. I use a short stitch to make sure it doesn't happen and can never understand why it happens.
I don't get it. Mine never open. I was thinking maybe it was your stitch length but if you use a short one that would not be why. I don't even back stitch and mine are strong and never unravel. Maybe your tension, is that a possibility? I'll keep thinking. Did you go to the site that is first mentioned in this decussion. Maybe it says something there. Because I really don't ever backstitch and never have unraveling or anything. ;)
