I saw this idea, back when I was a senior in college. Brilliant, your headphones wont tangle, and no more fighting over who’s headphones are who’s when yours look like this. I always called this knot a turnip, but I guess its mostly called chinese staircase, its the easiest thing to do, with the prettiest effect. I am not going to lie, it took me a few hours to finish this headphones, but it is so worth it. I chose whatever colors I wanted. Some people use color fading string so they wouldn’t have to switch colors but I didn’t have this choice. I can’t explain my methods but here are some methods you can try.
I used one string at a time, tied knots and switched off colors, I didnt wrap other colors underneath, you will find the method that works best for you.
