Marmar, I love your attitude! "these mistakes are too much fun to do only once!" You are absolutely right on!
One more suggestion that I haven't seen unless I've overlooked it which could ceratinly be, is to slow way down at the end of the seam. Hey, it couldn't hurt. I'm usually in a hurry and want it done, like, yesterday! I think I'm my own worst stitching troll! I'm sure there must be a troll living under my machine that's playing havock with my seams. Couldn't be me!
