This is the box I made from the walnut plank that I resawed for the previous box bottom. On this one tho I sliced off a couple 3/16" pieces of curly maple and glued them for the top, bottom and inner guides. The green tinted resin is visible with the end picture showing thru. The side was blocked by the inner lid guides.
This walnut is the tainted, marred, scarred or maybe just mineral growth absorption before the tree was harvested and I have to say, I've never had walnut a dark nor black streaked like this batch. Whatever it is, it makes for a magnificent appearing piece of lumber.
