Trees for Cities Xmas card

This was my first ever self-initiated 'run' work and I still love it. I admired (and still do) what Trees for Cities were doing so set myself the task of making the most environmentally sound xmas card possible to see what they thought. By using the postage as the 'xmas tree' design and a fold at the bottom, to minimise the amount of card normally used, I came up with a pretty nice solution. Each 'tree' is made up of different stamps, depending on whether it's first or second class. Anyway, Trees for Cities loved it and so did everyone on their xmas card list.
