You will need
A plain wooden box
Screws
A ruler
An (Electric) wood scraper
Antiquing wax
An old rag
An old rag
I started by carving straight lines into the wood so it would end up looking as though the box was built out of small planks. I did this by dragging a sharp screw through the wood along the ruler. When that was done, I made several scratches and dimples with different sides of the screws, but then my dad gave me his electric wood scraper, so I used that to do more damage.
At this point it doesn't look all that great yet, but here's what will make a world of difference: apply a layer of antiquing wax all over the box using an old rag. It will darken the whole box whilst leaving the wood structure visible The was will also sit in the pits and scratches, thus accentuating them.
Be sure to let it dry and air properly before using it!
Sincerely,
R.
