How to make a mummy costume
On a budget: Dress your child in a white T-shirt and any colour trousers, then wrap toilet roll around their body. Kids love it if you stay still while they spin around wrapping themselves up in the roll! A bandage around the head is a nice touch and you can paint any part of their face that's showing with white face paint. You could even attach some 'treasures' to the mummy's bindings, just like a real-life mummy!
