1. First, take string rope or yarn through your pipe and secure it with a knot. Begin cutting strips of yarn and tying knots around the copper piping, working your way across the length of the pipe.
2. To secure the yarn to the pipe, fold the piece of yarn in half, forming a loop at the top. Pull the ends of the string through the loop and tighten. You can experiment with different knotting options. While below you can see that I wrapped the loop over the top of the pipe and pulled the ends through, in the next image down you will see that I ultimately preferred to bring the loop under the pipe before pulling the ends through. Either way, works.
3. Now switch colors and continue knotting. The finished product is more interesting if you vary a number of knots you complete for each color of yarn. I couldn’t wait to introduce the neon orange yarn into the design. This much-needed burst of color really brought the project to life! Since I knew I wanted my wall hanging to have an angled look, I began cutting smaller pieces of yarn as I worked my way across the pipe.
4. Below we see another view of the knots and strands. This project went very quickly. You can easily create one of these wall hangings in an hour or less. When I’d finished tying my knots, the wall hanging looked like this: Give your wall hanging a trim!
5. This next phase of the project is by far the most fun. Now give your wall hanging a trim! When you finish with the knots, you will likely have an uneven collection of strands, and you will probably want to emphasize an overall shape, be it angled to one side or toward the middle.
