I'm a pretty advanced knitter and can do a lot of other high-end crafts but there are two things I have been a complete failure at: crochet and pom pom making. I've given up on crochet but these pom pom makers from Clover have saved me on the pom pom front. I purchased the small set at Joann's and it was like a miracle for me. I was previously failing using the cardboard and fork tine methods (miserable results) and was not hopeful that I'd be able to "get it" with the Clover either but my first pom pom was very fluffy and exciting. I made several after that, all with great results. So when I was making pom pom peds, I needed the extra small pom pom maker to get the pom poms exactly the right size for the socks. I purchased the extra small set on Amazon - the price was right and I couldn't be happier.Each of the sets I have contains two sizes. Very easy to work with and perfect pom poms every time!
