At tradeshows, we always had designers asking for Chinese Knotting Cord. One year we decided to do something about it! Chinese Knotting Cord is made from braided polyester and is also known as "braided nylon cord". It is not silk, though may be mistaken for it - it has a nice sheen and is very durable, making it a great choice for knotting and weaving. It holds its shape and will not fray if the ends are sealed with a lighter or thread burner. It is used in many types of beading, weaving, stitching, and macramé, and can also be used anywhere a high strength cord is needed for crafts.
