So, my thoughts.
The White Gum Wool is stunning and I will be knitting with it again.
Like all Kate Davies patterns, this one was well and clearly written, but I had to reknit the collar,and the left side still looks a little odd. I hope it will settle down after a little bit more wear.
I choose the music note tape top cover the steek, and I think it looks great.
I deliberately chose low contrast colours for the colourwork. I think it looks quite nice, but I would also like to make it in a higher contrast. Although I won't be reknitting this, both because I rarely reknit things and because of the issues with the fit.
