The Woodland Trust are promoting a lovely scarf you can knit yourself, that doubles up as a way to measure ancient trees and help them build a record of where they are. The idea is that you use the scarf to measure the tree's girth and send them info if its big enough to count as 'Ancient'.
Perhaps we could do this in Kew - anyone know of some big old trees to measure? Oaks, beech, that sort of thing.
I suspect due to Christmas overeating I will also classify as an Ancient Tree. Hopefully all that knitting will help to burn up some energy. Plastic bags can be used as yarn , so we could actually use up old bags with this.
