How much yarn do Machine knitters really need?

Unpacking my coned yarn stash and attempting to organise it.
I had to move a whole studio worth of my machine knitting stuff into my home. It’s taken me months to have enough energy and get up and go to do this as I have a neurological condition called FND (Function Neurological Disorder). It can effect my energy levels, my speech and I can loose sensation down my whole right hand side so I look like I am having stroke but the effects are temporary. It’s very frightening for anyone seeing this happening who doesn’t know what FND is and can do.
