I started on my 1860s corset today. I'm making the first mockup pretty much exactly as is from the 3 pages x 3 pages blow up of the pattern pdf, except that I decreased the bust gussets by 3/8" on each side, since the ones in the pattern seemed so huge. I already cut out everything, and sewed all the pieces together, so tomorrow I just need to tape bones in and try it on. I'm still trying to figure out if I want most of the bones to stop at the waist or not, since I've seen extant corsets with both types of boning patterns. Also, my mockup looks crazy, because it's made out of three different colors of leftover canvas scraps. I just hope it winds up being a pretty close fit!
