Most people bind off as they are working that row. They knit 2 stitches, pull the first over the second, knit one more and keep on in that manner. Mary just keeps going until she doesn't have enough to work another row. Luckliy she does a lot of arm knitting or ruffle scarves, so we are only working with 8-10 stitches per row. Since I know it would really confuse her, I just have her slip all but two stitches back and then work a bind-off almost as you normally would. She just slips where most people would knit. I got to teach this bind off to someone at Wed knit-night.
