The video demonstrates a technique for working with Chinese knotting cord to create a bracelet by turning the cord into a needle using a two-part epoxy. The process involves mixing equal parts of epoxy glue and hardener, coating the cord with the mixture to stiffen it, and allowing it to dry straight. This method simplifies threading the cord through a chain, preventing it from fraying and making the weaving process more efficient. The technique is highlighted for its simplicity and effectiveness in jewelry making.
