I finished the eyelets on the back of my stays! This was the period when they switched between spiral and cross lacing. I went with cross lacing, as that was what was marked on the pattern. I also made the pockets for the bones in the back panels. Which meant I was able to try the stays on!
The fit is good, and I think it will be even better when I have shoulder straps on it and have finished the cording.
So much cording! I've made good friends with my washable marker.
