Made my very first pom pom a few weeks ago. It turned out to be so easy and a really excellent way of using up scraps of yarn.
I'm going around making pom poms as and when I feel like it now. I've made four more since, and two have been attached to an elastic to be used as a hair tie. The other two...I'll decide later.
But these particular pom-poms were attached to the end of a scarf done in a cabled pattern that made it look like it was braided. Real easy pattern and you can pretty much knit it up on auto-pilot when you've memorised it (which is not hard at all)!
