taketimetosew, i know EXACTLY what you're talking about. i have a singer engenuity(sp) i have spots that are perfect, top and bottom then i have spots that look like the top tension is 0. i know if you change directions too fast it will do it, just about the time i get a good rythm going i run out of room or bobbin thread. in other words.i feel your pain. the one i'm working on now i'm going to finish then look at the back and take some of it out and do it over. some of it i will just have to grit my teeth and accept becuase i can't aford a longarm (machine or quilter) and i aint gonna live long enough to do them all by hand. i know i didn't help you any but at least ya know that it's not just you! LOL
