I'm still building up to restart this great hobby after a long time away, and looking to build up a few essentials to get me going. As far as small paint pot storage goes I've seen a few things like nail varnish holders, which some people use, so my question is what shelf depth in cm would be adequate to hold Humbrol and Tamiya and other small pots. I've read 3cm, that sounds a tad small for the pot diameter! Cheers
