That is awesome! Tutorial? Hehehe
Is there possibility the cable would weaken and the core to break?
What is the current length, braided?
Yeah, it's great, glad you liked it. I took the idea from a youtube video where some guy braids his long Ultrasone cable. On the video, he shows how to set up the 3 strands in parallel then begins braiding. I couldn't do the braiding, so enlisted my girlfriend to do it. She said she may do a tutorial, but isn't dressed for it at the moment..
The cable currently measures about 142cm, which is about right. You could do it longer or shorter depending on where you start the braid.
