Mason jar hanging candle holders. Use sand instead of pebbles. Some jars can be coated with glass paint to match colored bottles. 12 quart size jars are about 11.00. Suggest different sizes. Small jelly jars are "quilted" creating a faceted glow from candle.
DIY: Hanging jar lanterns. The page gives you a link for the chained lid hangers pre made. I say use an awl and put your own holes in the lids then run chain or whatever works through the holes. This page has several mason jar crafts. Brilliant really.
