In my opinion these are the best pom pom makers on the market which is why they cost a little more than most. Designed by Japanese crafts company Clover.
You can make two different sizes - 65mm and 85mm. There are full colour diagrammatic instructions on how to use them. When choosing yarn select an acrylic or wool blend they will 'fluff' up when cut. Avoid cottons as they tend be too 'flat' - hope that makes sense?!
