The only prerequisite for creating your own menorah is that it have the correct number of candleholders; below are two variations on the theme, each one as inviting and easy to make as the next.
For a festive spin on nature, find a fallen branch at least 16 inches long, with a raised knot for the shammes. Mark nine evenly spaced dots with a pencil, one on top of the knot; drill holes with a ⅜-inch bit. (Hole size depends on candle size.) Paint with silvery craft paint. Let dry and affix self-adhesive bumpers to the bottom if desired. Be sure to never leave the menorah unattended while candles are burning.
This modern menorah sets an appropriately reflective mood, and olive oil is a nod to the Hanukkah miracle. Cover top halves of eight small jars (use a variety) with masking tape. Using etching cream, etch bottom halves according to product directions. Remove tape. Fill jars halfway with water. Add ⅛ inch olive oil. Drop a floating wick into each jar, cork side down. Use a birthday candle in a small, narrow-necked bottle for the shammes.
