Choose 3-5 colors of yarn and make pom poms in three different sizes, varying the colors as you like (use less yarn to make looser, mum-like poms and more yarn for traditional trimmed round poms).
Wander outside and find some lovely dead plants that you can harvest the stems from. I used stems from last summer’s basil plants.
Trim the stems as needed and fit them into 3 or 5 (odd numbers look best) small bottles or vases. Decide the best placement of the different sizes and colors of pom poms.
Add a dab of hot glue to the tips and attach the pom poms to the ends.
