Episode 21 of What We Found, in which Cheryl discovers the scent of spent shotgun shells. Be glad "scratch and sniff" hasn't come to the web.
This is a U.S. flag made of items found at Table Mesa Road, where people go for target practice without the inconvenience of supervision and clean-up. The background is quarter-inch plywood, bullet-ridden. The red strips are spent shells. I made the blue field by applying cyanotype solution to some targets I found, and the stars are shotgun shell primers I removed. All the items used were found within a 25 foot radius, and there's miles of this junk.
