So I am sure we all have had issues with paint jars taking over our work space this is my solution. My original answer to the problem was this standing rack with a lot of holes to slide the pots into. It works great for all my vallejo paint, but sadly I did not have a large enough bit to fit the GW paints.
So now I have a huge rack to fill in as I get more
you could also add on a top and make it more ridged but I did not have room as it sits under the shelf at the back of desk.
