I finally purchased one of those Pom-Pom Makers (in a large size). Previously I made pom-poms with a strip of cardboard or a fork.
As other bloggers have said before me, the written directions, for the maker, are not user-friendly. I went on You Tube and found an easy tutorial.
On Pinterest, I've seen images of Pom-Pom Rugs which looked interested, especially in ombre shades.
