Thank you for the details of seaming and I can use these ideas when I put the sweater together.
Unfortunately, this is not a seam, it’s mid-sleeve after doing surgery to remove 3 inches of length. My husband insisted his arms were three inches longer than average!
I believe a seam in the middle of the sleeve will look odd and be especially difficult to create an exact row match to the other sleeve.
In theory I should be able to figure out how to graft it together, however, the complexity of the way the threads weave together is throwing me right off. Even using a different colour yarn to track the path is a visual nightmare.
It might be easier to reknit the sleeves starting from the raglan down to the wrist - then, I’d need to figure out how to decrease on each side (instead of increasing as I did originally). Oh what fun! (she says with sarcasm and wistfulness…)
