I was looking at a spiral woven basket and the idea came to me of a shell form using junk material on one side and offcuts on the other. I was in the process of lifting my plasma cutting bench off the floor so I didn’t have thousands of small off cuts underneath and these are what I used to give that close grained texture to the other side. The last element was an old wagon wheel rim which was in the pile for years and it was almost the ideal size for this piece.
