Single bind/cast off
Slip first stitch on needle and knit the follow-ing stitch.
Using the tip of the LH needle, pass the slipped stitch over the knitted stitch.
Knit the next stitch and with the tip of the LH needle pick up the first stitch on the RH needle and pass it over the other knit stitch, so we are left with only one stitch is on the RH needle.
After all the stitches have been bound/cast off, cut yarn, pass end through the inside of the last stitch and pull firmly so that the stitches don’t come loose.
