Day 5: I’ve gone back to the first shoulder, and picked up the cast-on stitches.
I could have done a provisional cast on, but I think that doing a regular cast on and then picking up those stitches might give the shoulder “seam” a little more strength and stability. Everything hangs from these two points (the shoulders), and sometimes the provisional join in this area gets a little stretched or stressed. Even this won’t be as stable as shoulders with the reinforcement of a sewn seam, but I hope it will help a bit.
I then knitted the first rep in the new direction.
