Lots of paints to store

I have two wooden racks storing over 400 paints. One is a flat piece of board that has been furnished with 2 inch pieces of dowel just the right distance apart to hold a tube of paint by the shoulder. This board carries tubes of Matisse, Jo Sonja and Windsor Newton water mixable oils, all in one easy to get to place - a wall in my laundry. The full range is on the wall in one place and in the same order as the colour chart. Each place is labeled so when a tube is missing I can easily see what is either in use, missing or in need of replacement. For my bottles I have a cupboard that is one bottle deep.
