Instructions:

1. Take two strings and tie them together at either end; using the glue-gun (or a strong glue) attach the strings to the back of the mask and leave to set.
2. Paint the mask whichever colour you like, then decorate it similarly; glitter glue could be used around the eyes for example.
3. On the foam sheet, use a pencil to sketch whatever numbers/letters for the top of the mask. Cut them out, then apply glue all over followed by glitter and leave to dry.
4. Once the glue has dried, shake off any excess glitter before using glue to stick them to the top of the mask.
