Here we go again. I might have said I've had enough of stays for this year but now I've been making new stays for mid-18th century costumes. I based the pattern on the oldest pair of existing stays in Finland and you can see themhere. The original is made out of 8 panels of pale brown linen (plus shoulder straps) and the 5mm wide boning channels are stitched in blue silk thread. With two small black-and-white photos of the stays in Dress of Gentlewomen in Finland in the 18th century by Riitta Pylkkänen and the one blurry photo from the web, it was a bit hard to imitate the boning pattern precisely. However, it's quite close to Garsault's fully-boned stay pattern featured (for example) in The cut of women's clothes by Norah Waugh.
As usual, I mix both modern and period methods for construction. First, after cutting all the pieces, I stitched all the boning channels by machine.
Then I sewed the panels together.
And then inserted the bones (cable ties) into the channels. There are 140 bones altogether.
More w.i.p. photos coming later on as I progress... :)
