Our eldest calls this her disco wallet. Small, just big enough for a pass and a little bit of money. Fits in every pocket or petite handbag. She takes it when she goes out to the teenage dance in our village. The first wallet was a present in a swap. Copying was not difficult. One fabric scrap of 12x18 cm, 10 cm of velcro and a small piece of ribbon. You could make 20 in an hour.
