Nearly finished! Last week I was knitting on three needles, and this week I was using four. Once the sleeves were on the same needle with the fronts and back, I found using a circular needle well nigh impossible because there was a tight corner to turn at each sleeve. The only way I could do it was with four needles. Once I was far enough up towards the neckline, the whole thing flattened out and I could get back onto two needles. Seeing the whole cardigan hanging from the needles in one piece is very entertaining. There is so little left to do now, just the button band.
And no seams! Just a little hole under each sleeve, five stitches across, to be sewn up.
