The hair is old, dry, bindweed hanging from a tree at Old Lady Pond. After looking at the picture on computer, I decided that it was a bit too flat, and would be massively improved by putting a big flower in the 'hair'. I went back, but suddenly found myself very popular with the killer (well - large at least!) bees which seem to hang about there waiting for my arrival. You'll just have to imagine the flower!
I might be avoiding the pond for a while.
