Paint both halves of an egg-shaped pressed-paper box with black acrylic paint using a foam brush. Let dry.

Using a glue stick, adhere black crepe paper to black card stock for added thickness. Using the templates, cut out two wings, a head, and feet. Cut out two wing outlines from gray crepe paper, and glue them in place. Using a hole punch, make two white crepe-paper circles for eyes. Cut two small white triangles for fangs. Glue them onto the head using glue stick, and dot the center of each eye with a red pen.

Using small dabs from a hot-glue gun, secure wings and head to the box half with a lip, positioning them flush against the lip. Hot-glue feet to the bottom of that half, so bat will stand.
