This rustic trunk was made out of some 1×4 pallet lumber that I picked up from a local farmer. The whole box except the top are 3/4″ in thickness, with the top being 7/8″ in thickness. To fasten the trunk sides together I used old fashioned fine cut nails that I dipped in vinegar to give a rustic appearance. I also dipped the hardware in the vinegar to add a little patina as well.
For the finish, I went with a nice semi-gloss polyurethane.
