Bind off, the point where every knitter finishes the garment or accessory they are working on by decreasing stitches and taking the loops off the needle creating a finished edge.
There are several ways to bind off:
Three-needle bind off is used when you don't want to sew a seam, for example when finishing a hat.
Regular bind off is most often used, two stitches are continually decreased until one stitch is left, then remaining yarn is loped through the remaining stitch and you are done.
Decorative bind off, like a picot bind off creates a decorative edge to a scarf or blanket.
And there are even more ways to work the above bind off.
A great book with several types of ways to 'cast on' (C for tomorrow) and bind off is titled Cast On Bind Off by Leslie Ann Bestor.
