Cast on Medium size. Did one extra mitre decrease for small stitch count. No bust increases.

Continue straight until 17.5” long.

St count is out slightly for body due to size shifting, divided for sleeves with 59/100/59

I really didn’t enjoy the collar instructions, particularly the ‘reverse for the other side’, but I do like the effect of the collar, and love how it sits. The instructions for joining the back of neck to collar was also really unclear. I just cast them all off and seamed.

I don’t really love the mitre on bottom of the sweater, but am hoping it will sit better once blocked. Sleeves will be without the mitre.
