I have also seen similar centerpieces that use epsom salts instead of sugar. You could also sprinkle a mix of pearls/gems. Sand (or sugar), faux pearls, a 3 candle. An easy DIY wedding centerpiece idea.
Here's an easy decorating idea to use as your centerpiece or to give as a hostess gift this Thanksgiving! Place a Pillar candle inside a glass container. Surround the candle with such as acorns, chestnuts or pine cones.
Make a festive feature of your Christmas place settings. Try wrapping napkins with twine rather than a napkin ring and finish with cinnamon sticks, sprigs or holly/rosemary or twigs spray painted gold or silver.
Beautiful center pieces or just around the house- rocks, flower of your choice (maybe string it to a rock by the stem so it doesn't float) in a vase, fill with water, add small candle and voila-on the mantle?
