The Basic Bind Off is the most commonly used method, especially for beginners. As you work each stitch, you will pass the previous stitch over it and off of the needle.
First, you will knit two stitches.
Lift the first knitted stitch with the tip of your left needle.
Pass this lifted stitch over the other stitch on the right needle and let it drop off of the end of the needle (psso).
Knit the next stitch so that you have two stitches on your right needle again.
Continue to repeat this process until all stitches have been bound off.
