@sadclown666 Ah apologies :) Yes cos then its just a slip rope.
Probably if done right, remember it is a dog lead so will have a little 'give' in it. Not like a solid rope. Its meant to give the dog a chance if it gets tight, all decent (none are decent...) choke rope type dog leads have 'give'.
Edit* You'd be better off looking thru yr wardrobe/bedding for something non stretch and plaiting up strips of cloth or sewing a long piece to make a better one if thats all you have
