I finally tried a couple of lidded boxes and here they are.
The first one I did is rather plain and although the joint couldn't be seen I didn't like as it was too plain so I burned the edge of the base just a bit. Just my personal preference.
The second box has a bit more character with the slightly curved walls so I didn't mess with the joint.
And, of course, the usual shoddy photography! Woo Hoo, I finally figured out how to post the pictures without using Image Shack!!!
