There was more finishing work to this hat than most because of the double knitting, but it was all easily handled one step at a time.
When I got to the end of the pattern, I knit a couple rows in the main colour (on each side, so to speak) and then was ready to cast off.
|You can see the two layers curling away from each other|
once they are put onto separate needles.
Then I put the dark yarn end onto a sharp needle and worked it into the back of the stitches between the layers as best I could. You don't have a lot of room, but you can still pull the layers apart even if they don't open up like when I worked in the light yarn end.
Then I had to go back to the top of the hat and take care of the slit from when I was working flat. I used the long tail from the cast on and mattress stitched just the dark layer. Also, instead of sewing one stitch in from the edge, I went half a stitch in. Since I didn't decrease a selvage stitch when I started working in the round, I didn't want to pull it in too much on the upper part.
|I'm working the yarn end in by switching to a sharp needle|
and pulling it through the back of the stitches. I zigged
and zagged a couple times and then left a long end between
the layers. If you do it right you won't see it from the
outside at all.
