I'm still figuring out what to actually DO with all the excess fabric an FBA generates. I lost my nerve on the HP Chameleon muslin (and got annoyed, and got a ton of marking) because while I figured out the Y-Dart FBA and how to tweak the great big dart and manage some added shoulder fabric, the waist was suddenly inches and inches too big for the skirt portion of the dress, and the pattern wasn't supposed to support gathering at the waist, and I couldn't see how/where to add a dart... Now I'm at the adjustment stage of cutting out the blank slate marigold and the instructions cheerfully suggest I won't need an FBA (in my dreams) and then suggests putting the whole lot of added fabric in the shoulder gathers. If it were an inch or two, maybe, but I need to add 3.5 and that's just not going to work, is it? Is it? Stay tuned! I guess I have nothing to lose but the muslin fabric - and precious sewing time.
