This is the follow up to Pattern Fragment 0, Pattern Fragment 1, Pattern Fragment 2, and Pattern Fragment 3.
Cut open the arm hole steeks, and joining new yarn at the top of the opening (after the shoulder seam), pick up stitches around the arm hole, at a rate of 2 stitches for every three rows. I picked up two extra stitches in the "corners" at the bottom of the sleeve and did not pick up a stitch from the shoulder seam.
Also, place markers where the shoulder decreases start at the bottom of the opening.
Knit 9 stitches, move yarn to front, slip the next stitch, move the yarn to the back, change directions, [1] slip the first stitch (again,) and work back to the "beginning of the row," at the shoulder seam. Work the next nine stitches, slip the next stitch, move the yarn to the front, change directions, slip the first stitch (again), move the yarn to the back, and knit across.
When you get to a "wrapped stitch" at the end of this "short row," pick up the wrap and knit it together with the stitch it wrapped, and then wrap the next stitch.
Continue in this manner until you get to the markers where the arm hole shaping ends, before switching to knitting in the round for the main body of the sleeve.
[1] | You could turn the work, but I do this part just by knitting back backwards. |
