I have several patterns that are missing pieces... I list them on a case-by-case basis. Most of them are missing small things like a cuff or the facing for a collar, etc. I always state this clearly, and usually sell them at a pretty steep discount, depending on what might be missing. If it's missing something super important, like part of a bodice or whatnot, I usually just hang on to them. Maybe I'll get crafty one day, or maybe I'll find another damaged copy of the pattern somewhere and will be able to splice together a whole one. ^_^
