Alrighty, before dfr's head explodes, I'll put up some more pictures. I think it may be done. I haven't flossed the tops of the bones, but I'm not sure if I want to. I used the narrow flower trim at the top edge, so flossing at the top might look a bit off.
It still has a few loose threads, mostly from ripped out stitching lines. Getting rid of all the thread after undoing a seam is really time consuming! The unpicking itself is fast, and really doesn't bother me; unpicking seams and changing them a bit is just a part of sewing. But getting all the bits of thread off? Annoying!
I took dfr's advice and removed the boning from the seams that go right over my bust, moving the boning channels to either side instead. I'd actually already created an extra boning channel just to the outside of those seams, and the other one I added to what's actually the facing around the front, so that's plenty sturdy.
The corset is quite comfortable, even with the extra waist reduction! There's something disorienting about putting it on and placing it correctly-- the waist tape is placed correctly, I just put it on a bit too high up when I tried it on before-- that's also why the upper edge was too high. I've mentioned before that my natural waist isn't the part of my torso that's naturally the narrowest; corseted, the circumference around the bottom of my rib cage is actually narrower than my true waist. And once the laces are tightened, it's almost impossible to deliberately pull it up or down. So I have to fight the natural inclination to place the narrowest part of the corset (the waist) at the narrowest part of my uncorseted torso (the bottom of my rib cage.)
So, the fit is pretty good, wrinkling is minimal, it's comfortable, and manages some waist reduction! I'm pretty happy with this one. It's either done, or done-except-for-a-couple-of-details. I'm wearing it, anyways.
This was the first corset I've used real grommets for. I haven't ordered from GrommetMart yet, and grommeting tools are generally quite a bit more expensive than eyelet tools. But then I found theLord & Hodge Size 0 Grommet Kit on Amazon. They didn't have a size 00, the 0 was the smallest they had, so I went with that, since it was so much cheaper than any of the other grommet kits I'd seen. I'll have to get size 00 tools eventually, but size 0 is even what Sydney Eileen uses, so it can't be totally wrong, can it? So I've finally used two-piece roll-and-not-split grommets.
