Failed to load media. I found a way around the slip problem. At first I was very frustrated because I couldn't get the little pieces of cable to STAY on my string, but then I decided to lift the cable just enough up to the white part so it stayed where it was and it worked! It's a bit fiddly at times, but if you're just working, it works really well. I also used a butter knife to help me open the gap a little more when I was in trouble.
