now my longest ones are 15 inches if I do the whole length down the front. Mostly I would not get the heavy duty ones and I'll tell you why. Since I have been using the coutil and sewing down the pair of herringbone I am getting a really firm garment. In this corset I am only boning the exact back and the front panels to 4 inches only (each side) course there is the section for the wrapped washers, then starting the section, so I am looking at 16 - 18 bones. (not the usual 40+) Why not get the strong ones...really why do it. Unless you like cutting thru the heavier plastic. Really no great reason to do it. you are getting a lot of support from the garment itself.

Ah yes the list of things not to buy until moving. So in the meantime a rubbermaid tote with garb folded in it? (like period only plastic instead of wood) Would have to be folded and not chucked in or you might as well go to trigger. (see fencing bag for definition of chucking in)
We could sew in my basement, move the power tools out of the way. get some tables, that way it would be free, have someone to go get pizza, fridge for drinks and sattelite tv or XM radio to listen to.
