I had two visible scars, one on each of the labia majora, that were about 3" long and 0.5" wide. Over the course of the first year, they changed from livid red and super obvious to paler and paler pink; at this point (4+ years post-op), I can't find them anymore. I believe they folded into the creases in the labia. I haven't tried using a mirror and spreading everything apart as hard as I can, so I can't swear they're gone, but at least they don't stand out anymore. Your scars may also fade quite a bit with time.
I don't know how Brassard did it, either - there were about a zillion stitches, and he *must* have joined together other sections of skin, but those were the only visible scars (nothing in the thigh creases, either). Maybe I got lucky.
