Antique teacups that have lost their saucers still make sweet gifts when fitted with candles.
Martha Stewart Living, December 2002
In a small pan set over a larger pan of simmering water, melt down old candles; clip the thermometer to the upper pot, and keep temperature at about 185 degrees. Remove old wicks with tongs.
Cut a piece of wicking to the cup's height plus 2 inches. Clamp one end to a wick sustainer; tie the other end around a skewer. Dip wicking and sustainer into melted wax to coat them. Remove and stick sustainer to cup's bottom.
Pour in the wax, stopping 1/2 inch below the cup's rim. Allow wax to set, about 1 hour. The candle will harden with a well in the center. To even it out, use another skewer to prick a circle of holes about 1/16 inch deep around the wick. Pour in melted wax until surface is 1/4 inch below rim. Cut wick.
