A Stone in Hand. I have heard about an old rural principal, how farmers always came home with a stone in hand. In this way, over time, their field is cleared of one more stone while providing one more stone for building.
Over a period of a few weeks, I picked up discarded chairs while on my way home, slowly collecting the many legs that I needed.
The chair was originally for an exhibition, for which I had deadlines. As time ran out, I got on my bike and went and collected up the remaining legs. This was the last trip I made on this particular bike, as it went missing later that same day and since then, I have not come home with any more legs for building.
