Rigid heddle looms are small, simple, and satisfying. 

They combine three different mechanisms from multi-shaft looms (the reed, the beater, and the heddles) into one piece (the rigid heddle reed). This makes weaving on a rigid heddle loom easy to learn. It also means rigid heddle looms are fast and simple to put a new warp on. You can measure, wind on, and thread a new warp in a couple of hours, compared to the often multi-day set up of floor looms.
