I just built some shelves and used 1/4" and didn't like it. I was painted so it wasn't a big deal aesthetically. I'm thinking 1/2" would be better. I have a larger book shelf install coming up. These will be stained. The 1/4" didn't have very nice faces. What do you guys recommend for a built in bookcase back?
Actually, I dot even know yet if he wants them built in or free standing. Would that hangs the back design at all. I wouldn't think so.
