I am converting a very small bedroom into a home office and want to make the closet my "built-in" bookshelf unit. The dimensions of the closet are 6x4, but it isn't a walk-in. There are no doors on the front, so I trimmed the opening with 1x pine stained a deep honey, so it looks really rich. I planned on using 2x12x6 clear lumber (stained similar) as the shelves to hold everything from hoards of magazines to textbooks. Trying to keep in with the craftsman style, handcrafted look, how could I make shelves span that distance without exposing the shelf brackets and still hold the weight. Any creative ideas? I just think seeing brackets would make it look kind of industrial and wondered if there is any other way.
