Here are instructions on how to make your very own felted/fulled bag. For those of you who aren't familiar with the term "fulled", it's basically shrinking wool. You know that sweater you accidently shrunk in the wash? You fulled it.
Step 1: Knit 2 Circles
Loosely kint your piece. You can make whatever shape you'd like - I chose a circle. I used a medium weight 100% wool yarn and size 10 needles.
