Sleeves knit much better when you check both stitch count and gauge. Ripped out first sleeve attempt. Now working over 60sts to start (technically size M) and dec 2sts after 20 rnds twice. Switching colours every 7 repeats. I think it’ll work out. Current plan is to end with corrugated ribbing.
Eventually I get the code working to automagically link to the parent project.
