Work from right to left. Pass tapestry needle through as if to knit, drop st off needle 2. Just remember to keep the tension loose. The easiest way I have found for dealing with this is to twist completely the first and last sts of front and back needles before you start. I do not put knots in my socks, but since I knit exclusively with natural fiber yarns, my yarns are not as slippery as some.
Some folks swear by splitting stitches as they sew through and hiding yarn that way.
