Ever since going to college for art I have stored my supplies in fishing tackle boxes. Now you can buy all sorts of various boxes made for storing art supplies. But if you want to save a buck, go to the fishing section of the department store. Check out the variety of fishing tackle boxes they have there. I guarantee you will find better and cheaper art supply storage items there. I store my tubes of watercolor paint in a two sided somewhat clear fishing tackle box. On one side I toss in all my warm colors and on the other side, I store all my cool colors. It has little divider sections that are movable and removable. Pretty cool huh?
