I have made a really rough crate out of a recycled grape box from Chile.  I have featured the printed wood on the inside because of a box my father made. It was WWII in Scotland and 'waste not want not' was a useful adage. He made a box for my mother's letters out of a Scotch Whiskey box, the labels still cover the wood on the inside. Today I keep used postage stamps in his box. In my new box I am going to make some small books that fit like sardines and might include some other items of interest. Each binding should be different and maybe more experimental.
