Step 4: Using a Dremel rotary tool or a hacksaw, cut your arrow to the length of the exposed lamp pipe. Then, cut a slit down the full length of the arrow, and sheath it over the pipe.
Step 5: Run the lamp cord through the base of the skull and up the pipe. Attach it to the bulb socket, and screw the socket and halo to the pipe. Top it off with an appropriately rustic shade. (Bonus points: Make your own from brain-tanned buckskin.)
