I located a picture of spiderman, and drew/painted him on 24x 30 foam core board which we hung as a themed decoration in our patio area where the party took place. On another outside wall, I hung a giant spider web {which we use for halloween} and a spiderman glove and assorted webshooter toys. I made balloon centerpieces with mylar and colored balloons which we ordered, using lots of curling ribbon to hide the ugly brick bases used to weight the balloons.
