This is a sound idea in theory, to be sure. Not so sure it will be easy to achieve.
I got some nylon braided cord at Home Depot and it does not have a core. If there is a core like parachute cord I doubt it would be small enough. Maybe it is braided twine and not cord I am talking about. Home Depot has it in orange, yellow, white, etc... Whatever it is and it is about the richness of tennis string with a little tension.
