The next project was making these Wool Balls using Vintage Wool that my mom had given to me that was my grandmother's. Using the styro-foam balls, wool, and pins to keep the wool in place once in a while, and to change directions. Why use the styrofoam balls you wonder? You can get more decorations out of them, instead of just a couple. The star shaped one you definitely need the styro-foam star. These could be used all year long in one big bowl.
