Top 5 Ways to Match Up Your Socks

Some of my favorite ways to ensure that I always have a pair of socks that match.
  1. By color
    The gold standard.
  2. By weight
    You'll need a digital food scale or a mass spectrometer.
  3. By texture
    Use your feet, not your hands.
  4. By length
    Or width, but most people prefer length.
  5. By country of origin
    Or, if you prefer, land masses of the Cambrian.
