I always have a stash of bustle supplies handy. I use extra strong hooks. We hand paint large batches of them ahead of time with chalk paint. We always use strong upholstery thread.
After you knot the bustle and loop, make sure to cement the knot with hypo cement.

Here is a link to purchase the cement on Amazon. It is not cheap, but it is so worth it.
I hope this has helped you!
