Knitting -- finagling a sleeve join

If my description reminds you of any pattern you've used, let me know. I was between a rock and a hard place and did this to try to eke out some yarn.

It's Jaggerspun yarn; the company went out of business in 2024. I was using a cone of Maine 3/8 to knit a jumper and I knitted a lace motif from the antique Williamson stole (Shetland Islands) into the body. To keep working in the round, I did steeking at the top.

Normally when you do steeking you pick up around it and knit from the top down, but I couldn't do the lace motif in the sleeves that way, I had to knit from the bottom up. To test whether I might have enough yarn for two full length sleeves, I knitted one of them close to the length I wanted, then cut the yarn. Then I knitted the other one. 

Now the problem was how to join them to the body around the steeking. I supposed faggoting would have worked and maybe I'll try that some other time. But this time here's what I did.

I had underarm stitches on holders.

I did not cut the yarn when I finished the second sleeve. I cut the steeking and pulled the yarn through the stitch at the bottom of it, then went around the whole steeking pulling yarn through each stitch, the way I normally do.

I turned the sleeve inside out and put it inside the body so the wrong sides were together. 

Then I knitted off all the stitches around the steeking with all the stitches around the sleeve, the way you knit off at the shoulders of the body of a jumper. 

At the underarms, I did Kitchener stitch to close them, and closed up a couple of stretched stitches.

I'm still working on the second sleeve hoping against hope that I have enough yarn, but this post is about the sleeve join, and here's how it looks.
