I picked up a copy of the new Carpe Denim (Brit Eaton) 2012 Rental Archive at this years Inspiration show. Some really incredible stuff in this volume. Click here for Brit's website.
Burlap/denim candleholders were used in the late 1800's. Miners would put the candle through the fabric to prevent the wax from dripping on their hands. Here are a few images of the holders that were found on the last journey with Mike and Charla. I also included a photo of some fabric that was found. More photos on www.denimbro.com of the trip.
