Party Game. An old navigation map glued to foam board with letter cutouts. Add construction paper to make the airplanes and the game is complete. Using glue, a picture frame and a map I already had, the entire project cost only $3.00! Definitely within the party planning budget. I purchased the construction paper, letters, and foam board at the .99 cent store. Super easy and inexpensive.
Target golf game. Easy to make, lots of fun. You could have different slots for 1 or 2 pieces of candy and have the skinny slot be for the prizes. They keep trying until they get it in one of the slots.
