So the jumper is all done. I found this lovely series of videos on Youtube that goes through the entire process of constructing a raglan sweater, very helpful and some good advice for next time, since I only watched them to check about making the yoke section and had already knitted the main pieces. Here are the body and sleeves prior to joining together. I think it may be a feature of being left handed but my knitting in the round always comes out inside-out.I do not own any stitch markers and since you need to mark the point between the body and the sleeves for the decreases I had to improvise some; these are made out of plastic bag ties:
Here is the jumper pieces together on the circular needles.
And here it is all finished and tidied up. It was a bit worrying that when I did the decreases I found that, even though I had been counting rows very carefully, by the time I reached the neckline I had the wrong number of stitches, but I carried on regardless and hoped it would come out ok.
And it fits.
