I finished something! Technically it was pretty much finished last year I just had to block it and add buttons.
I cast off around the neck too tightly and it is a bit gathered (and it looks a bit odd when it is on and buttoned).
I did find a nice stretchy cast off for the arms (although I did a purl version). The pattern is from here and the yarn is Jo Sharp Desert Aran cotton (in parakeet). I can’t say I liked the yarn the ends kept fraying and ball kept tangling and falling apart.
