Re: Varnish brushes
I assume you're talking about a single-pack varnish like Epifanes??
If so, yes, hanging it (not just chucking it in a tin) in mineral spirits overnight is fine. If you just want a break for lunch, wrapping the brush as-is in plastic wrap and keeping it out of direct sunlight (or, even better, in the yard fridge!) will keep it for an hour or four..
