One of my pals sent me a website that had this free pattern. I thought it was a perfect way to use up some scraps from wool felted sweaters. I was especially motivated to whip one up because my little one LOVES balls. He keeps finding the hard wooden balls from the zig zag ball drop I made. I hear "GO" and then crashing. And then squealing. Wow, we need more appropriate indoor balls. Perfect solution right here.
