Sometimes, it's inevitable that your cords might fray throughout the process of tying and twisting. It happens to everyone in this craft, but there are a few effective ways to prevent it. Here are your options: 1. Taping the ends of your cord: Use masking or painter's tape to wrap the ends of your cords tightly. This helps to create a barrier that prevents the fibers from unraveling.  2. Apply fabric glue: Use Fray Check or any fabric glue by applying small amounts to the end of the cords and letting it dry.  3. Use heat: This is only applicable to synthetic cords. Use a lighter to melt the tips of the cords, just enough to create tiny solid beads.
