I love that method, and have used it exclusively for years, but the best thing about Ian's site is the explanation of the Granny Knot: http://www.fieggen.com/shoelace/grannyknot.htm

So many people walk around assuming they need to do complicated double knots to stop their shoelaces untying themselves. If only they knew they were doing Granny Knots, and that a standard knot is perfectly secure if tied properly.
