For the partyfavor bags, I purchased the the Spiderman giftbags. I made Spiderman coloring books for the boys and Spidergirl coloring books for the girls. I used various spiderman or spidergirl coloring pages and had the books bound at a office supply store.  For the boys, the cover had a picture of Spiderman that said, "Happy 4th Birthday Frank" and the girls said the same thing except they had a picture of Spidergirl. I also made the backpacks for the girls and t-shirts for the boys. I purchased canvas backpacks and had a graphics student that I knew to design a graphic which would read, "I had a Spidey good time at Frank's 4th Birthday Party." For the boys, there was a picture of Spiderman with his web and the themesong written inside of the web. My son's name was in bold print that looked like a spider.
