Welcome Mark. That is cool, the idea and concept of common distance separation of the conductors and use of cotton as a dialectic.
This is a very cool place - glad you found us. Once in a while, one of us does/says something that goes against the grain of another's opinion - but that's cool. No worries. We're all here for the right reason. OCCD (Obsessive Carver Collecting Disorder). That unique audiophile disease.
Welcome, and pictures are good - they never have to be perfect. With smart phones, it's so easy to insert a picture in a thread, hear. Use the fourth icon from the right, at the top toolbar of the default editor. It will put the pics in your post, in-line with the text, and automatically resize them. Just follow the dialog box. (the "attach files" option is a bit more clunky.)
As I looked at the cotton dialectic idea, I was thinking it would really look interesting dressed up with some TechFlex sheathing and some adhesive-lined shrink-wrap to dress the interconnect ends. IT comes in different sizes, and may also compress your cotton a little, making it more robust.
Welcome, and keep us posted on your project.
