Further work on the shed has seen the Pizza tray take on a new more meaningful purpose in life.
In fact I've been quite pleased with using this way of making a building as an experiment. At times there were delicate stages, such as the Evostick melting the wall, or the door uprights in danger of going their separate ways . But in the end , as more and more plastic was added , the whole thing rose up in the cook like a pizza base should. Management is so far very pleased.
