Pom poms used to be so '70s, but they've made a comeback because they're the perfect DIY project: all you need is yarn, a circle of cardboard, and scissors. I found some photos on Pinterest of pom pom ornaments you can buy, and an incredible rainbow pom pom ornament, with instructions that required an actual plastic pom pom maker (hello, Ronco?), but the tutorial from A Lovely Lark was the easiest. You don't even need the cardboard donut, just wrap the yarn around your hand before tying and snipping! Love this!
