I was finished with the body and then decided to rip back and add a few extra rows of length, just because I have a longish torso.
When it came time to knit the sleeves, I tried something I saw Anna (Jadzeea on Ravelry) do. She knit two sleeves at once from the armholes on her sweater for the knit along. I'm using bulky yarn and several Denise cords clicked together, so I wasn't sure it would be a smooth transition.
The first few rows I had to be careful to keep my stitches tight enough, but after that it was like regular magic loop. In case you're a non-knitting reader, or my grandmother, I'll say that magic loop is when you use one really long needle to knit a sleeve or sock in the round instead of using five double-pointed needles. In this case, I am doing that with both of my sleeves at once, on the same long circular.
To do this I transferred the held stitches for the right sleeve to my circular as I would for magic loop. I then picked up the underarm stitches and placed a marker, as directed, then knit about 4 of the held stitches. Then I them moved them around on the circular where the top half of the sleeve stitches (starting with the one's I would be knitting next) were on the top part of the needle and the bottom half on the bottom. I made sure there were a few held stitches sandwiching the picked up stitches on the bottom half to avoid any underarm gaps in the knitting.
Then I followed the same process on the other sleeve, using a smaller circular and a different ball of yarn, to load them on and rearrange them. I then transferred the top stitches of the left sleeve to the top magic loop needle and the bottom stitches to the bottom needle, sliding them down next to the right sleeve.
It is not as easy on Denise needles because the cords are thicker and not as bendy and the connections sometimes break. I think one of my cord connecters and a few needle connections are stripped from years of knitting. I'm going to try ordering some replacement parts before seeking super long circulars in larger needle sizes because I think I'll be doing sleeves this way from now on.
