The KnitPro Nirvana Pom Pom Maker set (6.5 cm. and 8.5 cm.) is the ultimate pom-pom maker. Basically, the line of thought is: the bigger, the better. And yes, big pom-poms are better than small pom-poms, whatever you use them for. But be warned, if your kids get hold of them, you'll never get them back.
