I'm not so sure on the actual amount of time for this one I didn't pay much attention to the clock, but I know I spent forever on the pink one, at least that's it seemed like.
This would work great for headphones too. I just didn't have any of those laying around.
If there's enough interest in it I'll make a how-to I have process pictures just in case but I'm feeling pretty lazy right now.
I'm becoming re-obsessed with knots...stay tuned.
