I learned how to make yarn pompoms when I was a little girl playing a crafts game we had at home. Well, it was my sister’s game so she made almost all the pompoms, but I also learned by looking at her!
First of all, we have to make a cardboard donut the size we want to make the pompom. Then we cut a very long piece of yarn, and start covering the donut with it. We’ll need to be patient here because we have to cover the donut with several layers of yarn, and do it carefully so the yarn doesn’t tangle. When we reach the end of the yarn (or, if it’s too long, when we cannot pass it through the central hole of the donut) we have to cut the yarn following the biggest circle of the donut. The threads won’t fall because they’re still held by the cardboard donut. With a piece of the same yarn we make a tight knot around the threads to keep them together. Finally, we take out the cardboard and “comb” the yarn to make a perfect sphere.
And now, imagination!
