These pom pom makers are just terrific. The extra small makes the cutest little pom poms ever. There's no way I could have made the teenie tiny ones with cardboard, and they turned out perfect first time. I found the instructions that came with them weren't enough for me, but I went on YouTube and it's all there. It's such a clever idea, and I imagine that eventually I'll have them in every size available! I needed tiny pom poms for a project I was doing and was able to make them from odds and ends of yarn. Would highly recommend.
