I used longtail cast on with waste yarn to begin a tubular cast on knit flat.

4-5-2025 Back finished and about a third of the way on the front. I put markers either side of chart B so that it was easy to see the limits of the diamond.

4-14-2025 Front finished.
Knitting the sleeves two at a time once again flat.

4-28-2025 Almost finished with just the neckband to go, blocking and seaming. This wasn’t a quick knit but it was interesting and absorbing to work. The pattern stiches are easy to follow without the charts after the first few rows.

5-20-2025 Because of the weight of the wool i used a sewn bind off rather than a folded collar. Similar continuous look without the extra thickness.
