Superhero Theme Party Decorations Streamers are another staple for kid birthday parties. These streamers are inexpensive and easy to put up and take down. Choose colors that will go well with the theme you have chosen for the party. For instance, if you have chosen Mickey Mouse, any combination of red, yellow and black works well. Hang the streamers straight down from the ceiling or twist two different colors together to hang them swag-style across the room.
Buying a special birthday banner can be a nice touch to your birthday party. If it is a vertical banner, you will be able to hang it on the door to let people know that it is your party so they know where to go when they get to the venue. Otherwise you can hang a horizontal banner across the room on the inside to decorate for the party.
