Pardon the terrible sketch-up drawing, I downloaded it tonight and did this in 5min. My basic idea is to make a grain matched box (maybe lock miters). But I want to carry it one step further and bring the grain match from the sides up onto the lid. My drawing explains it better then I can (I think). Don't pay attention to grain direction in the drawing, I couldn't figure how to change it. I'm thinking I could have the inside edges of the box and the outside of the top mitered to make a crisp edge? I've never really built and box like this and I'm just brainstorming. Let me know what ya guys think.
