I'm doing a skirt that has 6 rectangular pieces, with triangular gussets (at least I think that's what they are called) inserted about halfway up the skirt (these go all the way down to the ground as do the rectangular pieces). What would be the best technique for finishing the seams? It's a light weight brocade with silk inserts. Would french seams be good for this progject, or should I just stick with using the overedge stitch (due to the nature of the gores and all that). I know this fabric frays A LOT. And durability is a very big concern of mine.
