About the rugs that inspired the socks:
Mood (sometimes spelled Muud or Moud) is a small town in eastern Iran. The town has a long textile history, and rugs from the area are generally considered to be of a very high quality.
Mood rugs use several different designs but share some common characteristics. The background of these rugs nearly always features a small-scale, closely-packed, repeated motif. This creates an almost tiled effect that is very soothing despite the intricate design. These socks build on this idea by repeating a single simple element across the entire sock.
