The back of this knit up so quick, I was thrown for a loop when I started the front - I had never done Wrap and Turn before. After almost a year I picked it back up and had to a lot of trial and error before I figured it out and just thought of it as short rows instead of a bias slant.
Horrified to find some moth damage on back piece when I picked the project up again after the winter, but I think I found all the damage and remedied it. Ended up about a skein short of what I needed (an inch of the cowl and the button band), but was able to pick it up at Rhinebeck from Harrisville.
The shortage explains why the sweater seemed a bit big when done - blocking helped a lot.
Finished with buttons I also picked up at Rhinebeck 2018: https://www-melissajean-net.myshopify.com/
