I cut a 8" strofoam ball in half and painted it - white for the baseball and orange for the basketball. A word of advice - if ever you want to paint styrofoam, just know that it takes A LOT of paint to get good coverage. Once dry, I painted on the markings of the balls. I cut squares of tissue paper, that I attached to the ball with floral pins. The plastic signs, I found in the section that sells the stuff for homecoming mums. I glued them to wooden skewers, and poked them in place. The ball figures are Christmas decorations, that I also glued a floral pin to, and poked into the ball. I pinned balloons into the center. The board, is just a cake board that I glued a 11/2" border of scrapbook cardstock around. I filled the board with spanish moss, to give the appearance of grass.
I think they would make great coaches gifts (or even a gift for a little sports fan), if you attached various bite size candies to skewers, and poked them into the ball at varying heights.
Well, tomorrow is Halloween ..... we're hosting a Halloween get together for our Cub Scout Den ... I'm busy thinking about creepy food, and exactly what I'm going to be making ...
