This idea is my favorite - the Woolly Sheep. With the help of the most awesome pom-pom maker I have ever had the pleasure of using (Clover Pom-Pom Maker), I was able to make a whole flock of varying sizes. Using this tool, you can skip most of the details in step 1, just do the make a pom-pom part. As a side note, I think that I have tried making pom-poms in all the ways that are out there from using your hand or cardboard as a guide to the concentric circles and a tapestry needle to a pom-pom tree to these Clover gems.
Ingredients: Pom-Pom Maker, White (and black for the black sheep), felt for faces, pipe cleaner for legs, and ribbon for hanger.
With the tiniest pom-pom makers, I decided that they would be just as fun a little snowballs.
Happy Holiday Needling,
