Easy project just something to keep my nephews occupied 4 a little while.
Bat pattern: http://familyfun.go.com/assets/cms/pdf/crafts/batsketch.gif
Mask pattern: http://www.firstpalette.com/tool_box/printables/superhero4.pdf
For the Bat: trace the pattern onto black felt, then cut out. Place two google eyes on the head part of the bat, and color a popsicle stick black and place on the back of bat.
For the Mask: Trace pattern onto card stock, cardboard, or whatever you have avaliable. Cut out then punch two one on each side of mask. Now color the mask whatever color you would like add a string and your done.
