You'll always be able to improvise a centerpiece with these candle blocks. Each face is drilled with a hole sized to fit a particular type of candle.
Start with a single 4 x 4 inch cedar post from the lumberyard or home center;cut it into 4 inch cubes. With an electric drill,make holes in the center of each side. Use a drill guide to bore a perpendicular hole, which will enable candles to stand straight and burn evenly.
Bit sizes shown are gauged to standard candle thickness.
Top to bottom: 7/8 inch bit for hand dipped taper; 9/32 inch for a stick taper:1 1/8 - 1 1/2 inch Forstner bit for tea lights and large tapers(sizes vary slightly); 3/4 inch spade bit for a Shabbat candle: 15/32 inch bit for a Christmas tree candle.
Sand the rough edges with fine sandpaper, paint,stain,or seal wood with tung oil.
