A few people have asked me don't I want to clear up the scruffy dray? No - it's a thing of beauty and it's still a home! I love their use of urban debris - visible in the dray are: plastic bags, paper bags, newspaper, notepaper, ball of wool, jay cloth, woolly upholstery stuffing, wipes and T shirt fabric. It starts as just ivy, then they bring in dry leaves, as it gets colder and wetter in come the more insulatery and waterproof materials. Smart guys.
