1. Download the free bat pattern and enlarge to size. Fold a piece of graph paper in half and trace patterns along the folded edge. Cut out the patterns and unfold.
2. Trace the bat pattern twice onto black poster board; cut out.
3. Draw around the wing pattern onto purple poster board for the contrasting wing trim; cut out.
4. Stack one of the bat cutouts on top of the other. Referring to the pattern, use the hole punch to make the eyes. Then take one bat cutout (this will be the back of the bat decoration) and punch holes near the bottom of the center of the body (to make holes for the chenille stems).
5. Adhere the orange glassine scrap to the back of the front bat (the one without the chenille stem feet holes) behind the eyes with spray adhesive. Glue the wing trim to the back of the front bat to extend 1/4 inch below the edge of the bat (to create a narrow purple border).
6. Score the front and back bats along the fold lines indicated on the pattern; fold.
7. Feed a chenille stem through a pair of holes in the back bat so the ends come out the back of the cutout. Hot-glue each chenille stem loop between the pair of holes.
9. Adhere the two bat cutouts together with spray adhesive. To reinforce the chenille stems, use hot-glue to secure the stem area to the back of the front bat. Attach bat decoration to chair by twisting the chenille stems around the top of the chair.
