Here are a couple of images that help give a sense of scale to the Woollen lines.
The round areas are common cotton grass, a plant that helps bind the surface of the peat and provide a place for other plants to settle in.
The 2010 line is now growing mosses and algae. The 2011 lines have some algae already growing on it in places with cotton grass seeming to benefit from the protection of the wool where it is nearby.
The 2010 felt was made using water and wool and a huge amount of volunteer time. The felt used in 2011 is needle felted by machines and is much softer and looser. It will be interesting to see how it withstands the winter weather.
