How difficult to build your own cables?


Just a project for fun. I would like to build myself a set of high quality RCA interconnects. Can one buy a kit with step by step instructions? I could not find any such kit online. Again, I'm not looking to become George cardas, just a side project. Plus, how high of quality could one build themselves?

YouTube links to videos of good cable-building projects would be great too! 
If you have good soldering skills, you can DIY interconnects. Years back I saw that Rega Couple was getting good word of mouth. And all it turned out to be is Klotz cable (often available in instrument shops) and Neutrik Profi RCA's. I built those, plus I've made some interconnect using DH Labs wire and Vampire RCA's. I've also built balanced cables using Mogami wire and Neutrik connectors. Good luck and have fun!
