I’m using polyester chiffon for the top layer of five bridesmaids’ dresses. I’m managing to handle the chiffon OK, apart from one thing! The seams are ruching up slightly. This means they look unsightly and the chiffon layer has ended up shorter on every seam than the skirt underneath.
I’m using a very fine needle and a small stitch, as advised, and I’m keeping the chiffon taught, but still the chiffon is ruching up slightly. Does anyone have any advice they can offer me? I read that thread can make a difference, but I’m not convinced.
