I love knitting socks from the toe up and one method I regularly use to finish my socks is the elastic bind off. This technique works well for sock cuffs or any other knit edge that needs a little extra stretch.
The elastic bind off is a slightly stretchier version of the lace bind off. It can be worked across ribbing, stockinette, or just about any stitch pattern. You should be aware that this bind off tends to flare out the edge slightly.
