Will anyone please share with me the correct way to sew a corset seam? I know that it is suggested that you use a flat-felled seam, and this seems understandable when the seam is for a single corset bone, but what about a construction seam where double corset bones will be used. What would anyone suggest is the strongest seam method to use in this case?
Someone has suggested that I sew a basic seam, which I should press open and then sew each flap down to create two pockets for the bones, but I worry that the seam won't be strong enough. Is there another way?
Also how wide do you make your seam allowances? Mine are at 1cm at present, where I have been using bias tape to make pockets for single bones, but I don't think that this will be wide enough for a flat-fell or even the second method. Any help much appreciated.
