I'm asuming there is no case. Wrap it in bubblewrap and box it snug, but not tight or too loose. Cut the box down if needed. If a bow shop idea for a box doesn't work, a box used to ship an electric guitar works very well. (@ local music store).
ALSO!!! I much prefer FedEx Ground over the Brown guys for care of handling, shipping faster, and are always cheaper! All Kinko's now take FedEx shipments.
