Second sleeve

I took better photos of the start of the second sleeve. I had 8 stitches on a scrap-yarn holder. The row after I knit that one, I started 8 new stitches of steek (which have already been cut in the photo below).

I knit those 8 stitches in the usual way, except the last stitch I knit together with the first pick-up on the side. And when I came round to the beginning I knit the last stitch on the edge together with the first of the held stitches. This helps to keep away those gaping holes that sometimes appear at corners.
I then did a round of pick-up-and-knit. It's different from pick up, in that you don't really put the picked up stitches onto the needles (as I did with the 8 held stitches, above).

You simply stick the point of the needle through the stitch you're picking up and knitting from. For my sleeves, that was the torso-side loop of the first (or last) steek stitch. None of the steek stitches are visible on the outside of the finished sweater.
And then you bring the yarn around as though you're knitting in the usual way (except that there is only one needle involved).
And then you've got a stitch.

My stitches occupy slightly more space than my rows (if I knit 25 st by 25 rows, it'll be wider than it is tall), so I needed to pick up fewer stitches than the full number of rows available. I worked out what I thought was a nice pattern, with even spacing between the rows skipped, but no skipped rows at vulnerable points like the shoulder top or armhole corners.

This is the first time I've done the calculation of where to pick up stitches and how many I should have. For previous sweaters, when I've picked up stitches at the shoulders, I have picked up every stitch and then been slightly surprised at how the sleeves puff up a bit. These shoulders (while not being perfect) don't have the puffy problem.
