I cut out the partlet last night and got the back half put together. The shell is a lightweight black wool reclaimed from a half-finished cloak. The interlining is a coarsely woven springy tan wool that I've been using up a little bit at a time for years and years. The point at the back of the partlet looked like it wanted to flip up, so I put a coupole of fender washers inside before sewing it up. I will hopefully finish it tonight and get some pictures taken.
