 Shoelaces - TheBestLinks.com - 20th century, Granny knot, Reef knot, Aglet, ...   (Site not responding. Last check: 2007-10-08)
One addition of a half knot to a half knot forms a square or reef knot, an altogether uninspiring knot for the knot aficionado, but a fairly effective one for the purpose of tying shoelaces.
The second combination of half knot to half knot gives a granny knot, a knot not good for much at all.
A simpler explanation is that if one ties shoelaces first by tying a half knot and then by forming two loops and tying another (as opposed to some speedier technique), and if one consistently puts one hand over the other (left over right or right over left) one gets a granny knot.
