How do you fold socks?

Lay the sox on their sides, one on top of the other. Fold the toe up to the top, then fold it in half again. Slip your fingers inside the top and pull the stretchy part around the bundle. Now you have a neat little lump that you can stack in a drawer or toss into a suitcase, and any time you grab a bundle you automatically have a pair.

Here is the military fold, but IMO it's more work than it's worth:

I only buy black dress sox and white sport sox, several dozen at a time, so I can grab any two of the same color and have a pair.
