There must be some good directions for how to do a twisted cord somewhere. Try a Google search for the term. My husband is an expert at it. It is akin to rope making only with yarn on a small scale instead of rope fiber on a large scale. You basically twist a few strands of yarn in one direction until they are quite twisted up, put those on hold somehow, then do it again. Usually you make three but can have different numbers of plys in your cord to work with. You twist all of those the same direction. Then you hold those 3 twisted together and twist them the other direction. DH uses a drill to twist but you can do it by hand. It makes a very professional looking cord. I don't do it, DH always makes any I need.
