All the boning channels are sewn down - all the external ones, at least, which leaves me the ones at center back near the lacing. I have started inserting the busc but didn't have time to finish before dinner. I'm using a spoon busc (because I had it around, it's the right lenght, and it will be pretty), but I will have to be very careful for it to fit at the lower center front.
I have a bunch of wild ideas to use this corset for another outfit, with a poofy white petticoat. Must. Focus. Fashion show first !
