beer bottle cap candles, burn 1 to hours ~ great for travel or to use when you're entertaining on the deck at night.soooo easy to make! These would make adorable little gifts bundled in a bag and tied with a string for stockings etc.
Have made sand candles with Guides a few times over the years - easy and effective. Ice candles are also fun. Pretty up your picnic table with an easy-to-make sand candle from the June/July 2013 issue of Taste of Home.
