when are you nearing the end of the warp and want to re-slay for a different EPI, how do you stop the ends from falling through the shafts and/or just pulling out of the back beam (I warp BtF) and losing the rest of the warp? Help, and thanks,
If you are still tied on, advance the warp a long way and cut your warp off without tension. If you have already cut the warp, release the brake and pull the warp forward with your hands as far as you need to, to preserve your threading.
Cut a dozen-ish threads at a time, then tie them in a loose knot between the heddles and reed- preferably a knot that you can easily undo. This should stop them from sliding backwardsa and falling out of the heddles.
