These lacy-looking candles are easy to make using wax and candle dye...or even old candles! They take a few days to dry so make them well in advance of your party.
  1. Wash and dry the inside of wax-coated paper cartons. (We used half-pint milk cartons and 64-ounce juice cartons.) Place on a cookie sheet.
  2. In a double boiler over low heat, melt clear wax and add candle dye in the color of your choice. (You can also melt candles in the color of your choice; remove and discard the wicks.)
  3. Estimate how much wax you'll need to fill each carton half full. Having too much wax is better than not having enough.
  4. Add a few drops of melted wax to the bottom of a carton. Immediately place a taper candle in the color of your choice into the wax. Let the wax set.
  5. Fill the carton half full with pieces of ice in different sizes and shapes. Pour enough melted wax into the carton to cover the ice.
  6. Let stand until the wax is hardened and the ice is melted. Pour out the water; carefully tear the carton away. Let the candle stand a few days to dry completely before using.
  7. Be sure to place the lighted candle on a holder to collect the wax as it melts.
