I spotted this video while looking at Saori weaving videos earlier. It's an infomercial for a rigid heddle-type of loom made by the Clover (Hana-Ami) Company from Japan. I've seen similar rigid heddle looms where the heddle rotates or rocks and looks like a block of wood. What strikes me the most is the efficiency in warping. The loom has a built-in warping board that keeps the warp in place and under tension. It's simply rolled onto the warp bar after the ends are snipped. I wonder if this type of thing could be adapted to other rigid heddle looms. The board/pegs would need to fit in the frame of the loom and also have enough pegs for a decent length of warp. It makes me think!
