Summarize this article in one sentence.
The bat’s head should be approximately 3 inches wide with winged tipped ears.  You can use the construction paper itself as the bat’s head, or black felt by using what you’ve drawn as a stencil and cutting around it. Outline both eyes with the white colored pencil and then fill them in with either the pencil, or with whiteout. Each wingtip should extend approximately 8 inches outward with pointy ends. Wings should extend approximately 2-3 inches past each shoulder.  Cut around the outline to create the wings. You can use these construction paper wings or create more life-like wings by using black felt.You can use your outline as a stencil to cut the felt into wings. Use white paint or whiteout to draw small horizontal lines within each wingtip. There are no set amount of lines to draw, but shoot for a minimum of 2-3 lines starting at the tip of each wing down to the center. You can use one pin on either side of the bat’s face, or place one at the top of its head and another at the bottom.  The wings should be left unpinned and should be sticking straight out about 2-3 inches past the shoulders. Pinning the bow tie may be best accomplished once you have already put on the suit.
