Lay out 6 white strings that are approx. 2 inches each. Place a 4-inch purple thread parallel with these string with the end of the purple thread sitting in the center of the white thread. Fold the thread over and use the 4-shape knot method to create a knot around the white thread and purple tail. Continue to know along the white thread until the desired length is reached. Some of the white threads should be visible from both ends.
Lay out 6 white strings that are approx. 2 ½ to 3 inches each. Thread a 6-inch blue string through the final knot of the purple strand. Place the blue thread parallel with the white string with the end of the blue thread sitting 1 inch off from the edge of the white string. Use the 4-shape knot method to create a knot around the new clump of white thread, the blue tail, and the purple tail. The white strands should match up where the white strands on the purple strands are (a little more of less is okay). Make about 1 cm to 2 cm of knots. Thread the blue thread through the corresponding spot on the purple strand. Make sure to have the purple in the final desired shape. Repeat until the blue reached the end of the purple strand. Thread blue thread one more time Through the purple strand.
Repeat the above step for colors green (attached to blue), yellow (attached to green), orange (attached to yellow), and red (attached to orange). The white threads should increase by ½ to 1 inch for each layer, depending on the angle of the curve. The colors ed thread should increase by 2 inches (more might be needed).
Sew in the last tail. Use a jump ring to thread through the top layer and attach a clip, beads are optional.
