I used to build them all the time as a business back in and around '93. But my company never really went anywhere. I seem to have this "do everything myself" when it came to building something as artful as a humidor. Here's my latest, just for myself. If you have trouble finding pre-cut cedar let me know and maybe we can work something out, because most places aside from charging you an outrageous fortune for spanish cedar, it will come in raw form. I pay $3.60 per board foot, and another place I go is still reasonable at $4.20.
P.S. It's supposed to look distressed, but the flash highlighted some of the wood between the cracks that normally wouldn't be seen. Unless of course you open it up.
