Bend back the pin from the back of the badge and cut of the sharp end with some wire cuttings (trying to stop sharp bits of metal pinging all over your bed). Place each badge face up and hammer a nail about 3mm from the edge to create a small hole (best not to do this resting on a novel as your book will end up with lots of little holes through the cover). Thread the pin from one badge through the hole in the next and, using a pair of pliers, bend the wire over to stop it falling out. Keep doing this until you have a row of badges joined together – you will need to make an extra hole on the last badge in line. Find a chain or piece of ribbon to go round the back of your neck. I took apart one of those silly chain belt things that sometimes come with trousers.
