I made this pine cone out of aluminum cans. It started as an attempt to make a radially symmetrical candle holder. The cans are decapitated, cut 8 ways at the top, and another can is inserted. A band cut from another can is then placed over the two to provide tension and ensure that they do not slip away from each other. After that is done, the aluminum between the cuts is bent away.
As it progressed, it started to look like it would perform poorly as a candle holder. I may still f0llow through with making one, but I am open to suggestions (including scrapping the whole thing)
