Binding off is what you do when you want to get your work permanently off the needles without it unraveling. You can bind off when your work is finished or to help shape necklines or armholes. The knitwise bind-off is the easiest and most frequently used method. You use it to bind off knit stitches. New knitters sometimes bind-off so tightly that the edge loses its elasticity. Remember to keep it loose!
