It's for static conceptual interior renders and won't be close to the camera.
Good idea about enlarging the texture resolution.
For the bindings, I made some cuts with the applied texture as a guide and converted them to splines. Did a circle sweep with fillet caps, added displacer noise (as you suggested), then adjusted the UVs to match. Not too bad for what I need.
Just need to flip a duplicate to the other side, connect/weld, give them some thickness and lighting hardware to finish it up, me thinks. The scene is filled with lots of other custom pendants, plants, furniture, etc so I'm confident it will blend in nicely.
