Hey Bill I told Catherine about what you suggested because she does that kinds of stuff. She had some small crochet thread but to my eye it still was a little large.
She also had a spool of Hand Quilting Thread and I think it'll work just fine.
You can see a small cable in that photo that has the elephant on the right fender so I took some copper wire and made one, like you said it adds a little character.
Thanks for tip Tex
