A short practical article from the "Shortcuts" column of Master Weaver on dealing with knots and broken warp ends. It advises leaving holding knots in place, tightening slipping ones, and repairing broken ends with a pinned piece of yarn tied behind the harness. After the cloth is off the loom, the knots are removed by darning in matching yarn alongside each warp end and cutting off the knot ("deknotting").
