Binding off stitches

Slip the first stitch without knitting it, then knit the next stitch.

With the left needle, take the slipped stitch and pull it over the knitted stitch, then let it fall. You have cast off 1 stitch. There is 1 stitch left on the right needle.

Knit a new stitch and with the left needle, take the first stitch on the right needle and pass it over the knit stitch. There is only one stitch left on the right needle.

Repeat this process until all the stitches on the left needle have been worked and only one remains on the right needle. Cut the yarn, leaving at least 10 cm, and thread the end of the yarn through the remaining stitch, which you then slip off the needle.
