Part I, roughly covering the drafting, can be found HERE.
Matsukaze Workshops FB page (which you totally should!), this project took much longer than it should have--a full year due to several setbacks. Trouble sourcing enough nice buttons for a reasonable price (since I needed around 40 matching buttons!), lack of sleeve then lining materials (I later found my lining material in a pile of stuff), running out of leather dye.... And of course, because it is a steampunk project rather than a historical one, it was lower on the priority list--so it didn't get worked on as much.
