I know it looks like a bird's nest now, but after all 900 of the new warps (on the right) are tied to the old warps (left), this mess will magically straighten out. The knots will be drawn through the heddles and reed and anchored around the breast beam. Trust me.
This loom was built with an extra 2 feet of length between the heddles and the back beams, so that I can put a low chair in the space behind the heddles and assume a comfortable posture while tying on.
