I've laid the pieces on the cross grain because the notes about constructing early nineteenth century corsets found in Appendix I in Corsets and Crinolines read, "stays are usually cut in four pieces, all of which are generally upon the cross, as this assists materially in making them set better to the figure." I'm all for things setting better to to the figure. The instructions were taken from The Workingwoman's Guide and my favorite thing about them is the author's credit, which reads, "by a Lady, 1838." Thank you anonymous Lady for taking the time to write down how you made stays.
These pieces will use 2 1/2 of the 6 linen napkins, and will become the interior layer of the corset. That will leave plenty of fabric for the exterior, and should allow me a bit of room to do some organized placement of the jacquard pattern. Yea.
Time to mock up!
