1. Create a bat template, either through drawing one yourself, or downloading one, printing it and cutting out.
2. Fold your paper or card in half and place the template on, making sure the correct side sits against the fold.
3. Trace around the bat template - a graphite pencil will be fine, the shininess of it will show up on the black card.
4. Cut around the pencil lines. Unfold, and pin or hang your bat for a spooky Hallowe'en decoration.
