How I did it: I cleaned the goblets with metal polish and a clean cloth. Then I filled them with Microwaveable Soy Wax for Containers (by Yaley; $6.99 for 1 lb.; from Joann) and used Pre-Waxed Medium Bleached Wick with Wick Clip (by Yaley; $2.99 for six; from Joann) to make elegant, long-burning votives.
Time: 1 hour, plus dry time
Cost: $10 for 1 lb. of wax and wicks
