Recycling old wine bottles - weave the twine through the set of three bottles in a figure 8 pattern. Fill with citronella, put a wick through a 1/2" stainless washer. I also used 6" PVC lengths (1.25 wide) with end caps, to cover the torches when not used - protects the wick and torches from getting rain soaked. And, I got to drink a lot of wine for this project. Chateauneuf, Cigar Box, Chateau Montet, Louis Jadot - better the wine, better the satisfaction with the end project. :-)
