I made this jacket last year based on the Burdastyle 11/2010 #131 Short Jacket pattern.
I had this fabric in my stash since forever, because I was too scared to touch it, since it was the most expensive fabric I ever bought in my life. That being said, I’m not really sure what it is. Mohair maybe.
I had bought a very small amount, which was just enough to make the jacket and a matching cloche hat (that lays in the unfinished pile). The only change I made to the pattern was shortening the sleeves to 3/4 length and used a large hook and eye as closure.
