Hi! You guys are partially right that its from a clothing article, but definitely not shoelace or shorts. I happened across this costume ornament that cowboys wear on TV, you know those medalion looking thingies with a rope looped on its back, and you can wear it like a neck tie? Sorry if I'm confusing you guys, but I don't know what its called. The rope thingy itself is quite thick and its about 8mm in diameter, and its pretty solid and tightly woven. Its not hollow, so it will be quite challenging to thread anything inside.
[Edit : just did a google on images, I think you'll see what I'm talking about if you searched for 'cowboy necktie'

]
So anyway, here's a small update. Hope I can finish before the dateline, but its not looking so good.
Test fitted some parts for the bottom of the neck : -

The rest of the WIP are here : -
