Here’s the finished blouse from the collar how-to below. Besides the grainline changes to play with the stripes (yes, there are very fine stripes on this fabric), I changed the sleeves to 3/4 length with deep turnups, and curved the hem on both the CF and CB so that there’s a 1″ dip.
I am going to knip some serious mode! Got this issue on e-bay and have traced a pair of pants. The muslin is under way!
