If your daughter is the one asking for a Spiderman party, ask her if she has any particular ideas in mind. She very well might want a typical Spiderman party, complete with red, blue, black, webs, and Spiderman himself. Or maybe she’s a fan of Ghost Spider, in which case you can go with white, blue, and pink. There are also party supplies featuring Spiderman symbols in a pink color scheme. So see what your daughter has in mind, and then go from there to choose your décor and other items.
