Woodshop Storage - Shop Cabinets - great article. recommends Sketchup
Material Storage: For storing shorter lengths of solid wood I built a stepped storage bin out of 1/2″ plywood that allows me to organize and group by length and species. For storage of longer scraps of solid wood and lengths of lumber that I am currently working with I have a wood storage system mounted on the wall above my scrap bin. This allows me easy access to whatever piece of wood I need. Sheet goods get stored against the wall.
