Ta da....Musselburgh is done.
I followed the directions and knit it to 18 1/2 inches before decreasing but it didn't do what the photo on the pattern shows.
Ysolda's has a nice deep brim. I wanted that look but didn't get it.
If I roll the brim I get a little beanie. I was out of yarn anyway so it is what it is. At least it fits. My first try was huge. This one is perfect. The yarn is also a win. It's Capretta in a special reserve 100 gram Woodstock colorway. It has cashmere in it and is is soft as you can imagine.
