Shell wind chime, a great diy project after a day of collecting shells at the beach! Each strand you do can have shells from different places you have travelled to. You can create small and longer strands depending on where they will hang.
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.
