After I got the pattern for my spencer worked out, I immediately started on another one and a pelisse.
First, I have plans for a red flannel spencer based on the following piece from the Danish Moden 1790-1840 book:
Here is the mockup. I need to work on the collar next, but I already have a good sleeve pattern.
Second, a long wool pelisse, similar (but not identical to) the one from the Kyoto Fashion book:
Here's what I have so far. I want to have a folded-over collar instead of a standing one. Also, I may arrange the braid differently than on the Kyoto example and have hidden closures instead of front buttons.
