If you've ever used a cord in your life, you know they're prone to tangles. Headphones — especially earbuds — are some of the worst. Clever DIYer Ada posted a crafty solution: wrap your headphone cables like they're a friendship bracelet and they'll become tangle-free.
If you know how to make the square/Chinese staircase knots required to make a friendship bracelet, you already have the requisite skills for pulling off this tangle-prevention headphone hack. If not, read this. You're essentially making a friendship bracelet around your headphone cables. While Ada used embroidery floss (which you can pick up at almost any craft store) to get the job done, you should be able to get by with a thin string. Embroidery floss, however, will provide you with a softer finish and a much wider choice of colours.
Ada's headphones took about a day to wrap in embroidery floss, so if that's more time than you want to spend avoiding tangles you should learn a handy wrapping method, make a cord wrapper or buy an AppleCore.
