Binding Off
Binding off is sometimes referred to as casting off. They mean the same thing.
You will need to bind off in order to remove your knitting from the needles when finished. It is also necessary to bind off stitches when knitting the armholes of sweaters and at various other times.
Knit two stitches.
Insert the left needle into the front loop of the first stitch you knit on the right needle, from left to right.
Pull the stitch over the second stitch on the right needle and off. One stitch is bound off.
Knit one stitch (you'll now have two stitches on the right needle), pull the first stitch over the second stitch and off the right needle. Continue until you have bound off the required number of stitches.
Sometimes a pattern will tell you to "BO in pattern". This means to knit or purl each stitch as called for in the pattern that you are binding off, instead of knitting all of them.
