These are the drums of Warp yarns waiting to go onto the looms.



The yarns from the drum have now been placed in the loom and threaded thru the the heddles which are little wires which lift the yarns and create the Twill pattern.



Here is where the work is done. The white thing in middle is the controler that has a punched card with the weave instructions, and tell the heddles when to raise and what color the next thread is.



No computer chips here. This is technology from the 1500's.
