Holding A Crochet Hook One-Handed Tutorial

I'm lucky enough to have a little strap to help hold the crochet hook to my amputee hand but this video shows how you can hold the hook against your knee, which will also work against a different surface.

Or you could, using an ergonomic hook (one with handles), try a vice to hold the hook.

Alternatively, these ties might work to hold the hook if you can stick them to a piece of wood or something that could keep the crochet hook stable.
