/diy/ - Do It Yourself

I want to make a wooden box that can fit up to 30 letters, and I plan to use out of maple or oak. I want to make it pretty nice, so I want to do some vaguely fancy joinery to make the corners nice rather than having exposed endgrain. I'd be using a 1*6 plank so I'm not sure how fancy I can get with the woodworking but at the same time it also won't be expected to survive abuse so could I just cut the corners to a 45 degree angle and glue them together?
