Well, thanks to fellow weaver's who blog, I learned how to do a snitch
knot and redo the tie-ups on my loom which were rotting away with every
step. I ended up using parachute cord. It seems strong enough. I burned the ends so the cord won't fray.
I also used a nylon washer on the under side of the treadle to make sure the knot won't pull through.
Yay! It took about an hour to do them all. Now I'm ready to weave on! Thanks again to all of you who post advice and instruction.
