Backlog: Slopers

The flat-pattern method of designing clothes (and perhaps for other methods out there?) necessitates starting with a set of basic pattern shapes called slopers.  If you draft these, and then cut and sew them, you have what looks like a shell (a bodice), a sleeve, and a skirt.  Typically, these are sewn in plain, undyed muslin and lack fasteners and finished seams.
