First of all, thankyou Kate for your reply, it worked well around the neckline (with a only a little bit of rippling! :P). Anyway I got 'creative' and decided to make a big (2 inches) piece of satin bias tape to go around the hem (by folding my satin into a big triangle) - I'm seeing it in stores and I had to cut it on the bias because it's a stretch top. I had it all pinned in beautifully, it was lying wonderfully flat, but when I sewed it, it twisted and rippled like nothing else! I had sandwiched the dress fabric in between the two layers of tape and was using my zipper foot to get it right against the edge and sewing through the lot. The more I sewed the more it twisted! Should I not use my zipper foot? I have a Brother and not a wide variety of feed - should I get a roller or walking foot or something or do I just need to pay more attention to the direction of the curve of the hem? Thanks so much,
Katy M.
P.S. I've never worked with bias cut anything before and the hem looks like the side of Kates bridesmaids dresses from hell but WORSE!
