My son had a Star Wars party when he was 4, and then again 2 years ago when he turned 7. The 1st one was pretty simple. We made light sabers with foam pipe insulation tubes and duct tape, and I used Star Wars rings to decorate cupcakes. When he turned 7, we had an awesome time since we made it a costume party. My husband was Darth Maul (thanks to a great makeup job by my SIL), I was Padme, My daughter was Queen Amidala, and my son was a young Obi Wan. His bday is in May so the costumes were pretty cheap, mostly from ebay. I also got Jedi training books with light saber pens for the favor from ebay. Most of the kids that came (and a few adults) wore a costume, but we had muslin and rope to make a quick Jedi tunic for the couple that did not. One activity was putting a pic of Princess Leia in a balloon and inflating it, and then throw it and about 20 empty balloons out to the kids. They had to rescue the princess by popping the balloons to find her. Another activity was getting to have a light saber duel with Darth Maul. For the most part they had fun on their own playing in their costumes. I always make my own cakes(or cupcakes), so I just made a couple of 13x9 chocolate cakes and painted light sabers on with frosting - it was really easy. Have a great time!!
