They also received their Jedi Training Certificate and the candy "loot" from the pinata. We also had the "asteroid hunt" in the house. The asteroids were made by filling a small Easter egg with nerds and wrapping it in aluminum foil (see below).
As each child left the party, we gave them a Star Wars character cookie (made from the Williams-Sonoma cookie cutters, which are still on sale!) wrapped in a cellophane bag with green "grass". I also was lucky enough to find Light Saber candy in the $1 bins at Target back in the fall. Each kid got one of those too.
If I had had my way with time and money, I would have purchased material to make each kid their own Jedi Robe... but I didn't, so nobody got one of those! But, there are great tutorials out there if you ever want to make a quick, easy, cheap Jedi robe! :)
