I recently purchased an older 4 shaft loom with 6 treadles (but only using 4 now). I had professional help with the sectional warping beam (all cotton rug warp), and then I threaded the heddles and reed and tie-up myself. So here is the double trouble: my heddle threads are crossed in several (really MANY) places, so I only have one shed out of four that is really clear. A second one is semi-clear. I have begun weaving but now see that some of the trouble is that the sectional beam warps are sometimes crossed behind the heddles. It took me weeks to accomplish the warp beaming, threading, sleying and tie-up. I uncrossed half a dozen of threads by snipping them and re-tying, but I cannot bear the thought of starting all over again. Shall I continue with 2 unusable sheds? Or...? Any help will be most appreciated.
