Your video is absolutely the best video on this issue. I used it about 6 years ago, and needed to refresh my memory. I have viewed several other videos which make this seem like a herculean task. I agree 100% with other comments, This is THE BEST blind repair video on RU-vid.
Jeff...come on! Even I, an old woman, knows you only join ends with a lighter to GUIDE the new cord through! Then you separate them! Duh!!! Watch it again and this time, pay attention!
