To create your own gleaming arrangement, generously cover the bottom of white paper bags with sand, which will keep them sturdy and stationary when exposed to the elements. Arrange bags in desired positions (the luminaries lining the walk above at left all 2 feet apart), and then insert tea lights or battery-operated LEDs.
Bright Idea! For a twist, use a hole punch to create snowflake patterns, or adhere letter-shaped stickers spelling out a holiday message such as "NOEL" or "CHEERS" to the bags. (Safety note: Never leave luminaries unattended, and extinguish the flames when finished.)
