I have been sewing for about 40 years (Yikes! I’m getting old) and know what I’m doing, generally. Anyway, I am making a wedding dress for my future niece. She has picked out a beautiful silk chiffon for the dress fabric, and it will be lined with a (also beautiful) silk lining. The pattern, Vogue 8150 with modifications, actually has the lining sewn as a backing for each of the individual pattern pieces (it has a bodice with princess seams), instead of constructing the lining separately then setting it in. This is OK with me, but I am not certain how I should finish the seams. At first I was thinking French seams, but am not sure how that would work given I will actually have four layers of fabric at each seam. I have a serger and was thinking that may be easiest, but I don’t want it to look tacky. Any suggestions? Thanks for your help!
