The the finishing Parnell knot, how do you tighten the loop? I use pliers, but tend to damage the string. Should I just use my fingers to tighten the loop? Then I pull the end of the string with same pliers. For the starting knot on the crosses, you're supposed to pull both ends of the knot's double loop How do you pull both ends? When I first started, I would use 2 sets of pliers. Then I just used one, and would just tension the other end with the drop weight. Now, I just sort of hand tighten, no pliers, and drop weight one side to tighten, and then yank the end of the string with pliers.
