Since everyone seems to use more candles this time of year, here is a neat tip...to remove the bit of wax left in the bottom of glass candle holders when the candle is done, put the glass holder in the freezer. I usually leave mine in for 2-3 hours. Then take a butter knife and slide it between the wax and the glass and it should pop right out! If it doesn't, put it back in the freezer for a little while longer. Also, be sure to let the glass holder return to room temperature before you use it again. Enjoy!
