I don't know if they still do it, but years ago you could go to a liquor store and get free whiskey boxes. They cut the tops on just 3 sides, so you had a "hinged" top. I have been thinking of getting some, then lining the insides and tops with a panel of maybe 1/4" plywood. Could then use as is, or put a fibreglass coating on the outside, so it would last longer. The really neat thing about these boxes is, each type of booze box is decorated with the factory logo, et al. Hmm, maybe I can find a picture or two.

Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
