We had a Christmas Tree Festival in our local church (which is also the village hall) . The trees were all done by individuals or groups from the village. This is just a small selection.
They use to do this at a local mall. the trees were all decorated by or for different charity organizations and they were raffled off the week before Christmas with the proceeds going to the organizations. They haven't been doing it the last few years. Not sure if it wasn't profitable enough to be worthwhile or if the mall management stopped co-operating.
