Shapes

• The shape of the invitation should be an instant giveaway that the party has a rock 'n' roll theme. One invitation shape to use is that of a vinyl record. Buy a package of small, black party plates and draw a series of thin rings around the edges using metallic silver marker. Make labels for the center of the plates which read, "Greatest Hits: Hank's Birthday Party," substituting Hank's name for the guest of honor.
  
  The invitation could also be in the shape of a jukebox. For a jukebox, use a square piece of paper and cut an arch shape at the top. Color it brightly and include the party text in the place where the names of songs would normally be found.
  
  If the guest of honor is a woman, make the invitation in the shape of a poodle skirt. Cut out a piece of pink paper in the shape a triangle with a curvy edge along the bottom. Draw a small leash and add a puff of cotton for the poodle.
  
  

Colors

• The colors that you choose for the rock 'n' roll birthday party invitations will help convey the theme. The outside of the card or part of the inside could include a graphic black-and-white checkered theme.
  
  Colors slightly darker than pastels can also be used, with or without the black-and-white checks. A light aqua blue, faded flamingo pink or butter yellow are also appropriate. Red, or red-and-blue with black-and-white also work for a rock 'n' roll birthday party invitation.
  
  

Text

• For the wording, use phrases including, "Fabulous Fifties" or "Sock Hop." Draw musical notes between the words, or use music stickers.
  
  On the back of the card or inside the card, include all of the rock 'n' roll birthday party details, including start and end time, location and directions, and a phone number that guests can call to RSVP. If you would like guests to dress to match the theme, remember to include that in the invitation. Encourage guests to partake in the costume fun by offering a small door prize for the best rock 'n' roll costume.
