These dainty teacup candles offer a way to reuse old candles. We've used this technique with seashells, sake cups, and more.
Candle How-To
In a small pan set over a large pan of simmering water, heat partially burned candles until melted. (Clip a candy or candle thermometer to the small pan; keep temperature around 185 degrees.) Remove old wicks with tongs.

Cut a piece of wicking to 2 inches more than a teacup's height. Clamp one end to a wick sustainer; tie the other end around a wooden skewer. Dip wicking and sustainer into melted wax to coat. Remove, and press sustainer to cup's bottom. Pour wax into teacup, stopping 1/2 inch below cup's rim. Let stand until set, about 1 hour. To even well in center, use another skewer to prick a circle of holes about 1/16 inch deep around wick. Pour in melted wax until surface is 1/4 inch below the rim.



This totally worked for me and was a good way to use up leftover candles. I didn't have a candy thermometer, so I just guessed on the temp, but everything turned out just fine.
Teacup candles will make some really nice gifts for special occasions like anniversaries or weddings. Nicely written out directions. Debra@scented-soy-candles.com
One Good thing to remember, THE WICK, should be the appropiate thickness for the diameter of the tea cup or mold. I have found that the wicks that are commonly sold in local craft stores do not work well---the wicks don't last, they drown in a pool of wax and go out.
