Of course my pompoms don't look as great as hers. She uses wool and I use acrylic. My pompoms tend to look more like fireworks! Especially when I make them in multicolors.
I love that I can quickly make 2 pompoms and as you can see, it is very easy to do multi-colors too! I don't trim mine extremely carefully, so they retain their handmade, messy look. It's a "Designer Element" and I am sticking to it!
