I made this walnut and maple box as a required project in woodworking school.  The assignment required splined miter joints, but the choice of material and box size was up to me.  I had previously found a small piece of very dark walnut with beautiful grain discarded in the wood waste bins at the school and saved it for a future project.  I don't know why anyone would have thrown this away because it ended up making a very nice piece.

The box measures 8"L X 5"W X 4"H and is finished with hand-rubbed boiled linseed oil.
