Gee, it doesn't sound like you guys have very many materials to store. I have a cheap, particle board cabinet; 5 feet tall 30 inches wide and 15 inches deep, with shelves holding 27 clear plastic shoe boxes and a few other containers. The shoe boxes are lableled in general categories (saddles and necks, dubbing, hair & fur, etc.) and make it fairly easy to find things. Each of the shoe boxes holding susceptible materials gets a couple of mothballs annually.
