After ruling up large grids of square-inch-ness to draw patterns on, I'm NOT DOING ANY MORE.
I've decided to go with the Elizabethan corset pattern, because dammit, I'm sick of ruling out squares and I can't find instructions on how to make the Florentine bodice (which I suspect would be much better).
So. I'll try to make it, and see how it goes.
If it doesn't work out, I will kick and scream and tear out my hair and end up wearing a strapless bra because at times like these, what else is there to do?
