I checked the link.....Martha's candles don't have much in the way of sand....just shape because the wax wasn't hot enough to penetrate the sand. I like medium sand....not too fine and not too coarse....then I get a crust of sand. Also...if the sand is too damp the cold water will keep the wax from penetrating so I make my shape and let it dry out a little before pouring very hot wax. I made Martha's flower pot beeswax candles a few years back. The were little red flower pots. Made from pressing real clay pots into the damp sand. I sold them but they didn't sell right away. I sold tons of my "Tidepool" candles with seashells in central Virginia. Those are by far the most fun sand candles for me. To each his own, but I like making things that turn out unique each time. And they are easy. I put a little can in the bottom of the sand before pouring. Keeps the bottom smooth and also makes it a safe place to have a wick. After the top is set up I poke a hole and insert a tabbed metal core wick with a stick.....it stays in place and when it burns....if anyone every burns these candles....it only burns into the can. A tea light can then be inserted if you want to light it again. The fun thing about sand is that you can be creative and make any shape you want. If you just want a round pillar.....just use a soup can for the impression in the sand.....a quart milk carton makes a great square candle...... You can even use a candle that you have to press into the damp sand......I don't like my husband's cat....but I don't think I should go there.....(smie)....Donita
