Wrap your headphone cords with embroidery thread knots – to make them tangle free! Visit apartment therapy for good instructions. Idea via ada:) on pinterest.

Use the following instructions via wikihow on making the ‘staircase’ wrap: basically you’re hiding the center cord with knots of the outside embroidery floss.

• Loop the first color. Hold two strings in one hand and the other string in the other hand. Cross the one string over and under the two. (It might look something like a ‘4’ shape.)
  

   

   

   

   

   
  Pull the thread through the loop. Take the tail, or end, of the ‘4’ by putting your hand in the wide space of the ‘4’ and pull the tail. As you tie the knot, pull the two strings in one hand horizontally, or parallel to your leg or the table. Pull the string with which you tied the knot vertically, or perpendicular to your leg or the table. The knot will rise to the top, next to the first knot that you tied.
