Hold the yarn in your palm with your thumb in between your index and middle fingers.
Begin wrapping the yarn around your two fingers.
Wrap the yarn many times around. The more you wrap it the more dense your pom pom will be.
Cut the yarn and place the newly cut end into the gap between your hand and the wrapped yarn.
Place the yarn here, this might be easier with a crochet hook.
Wrap the pulled through yarn around the outside and through the gap again 2 more times.
Pull tight and remove the yarn from the fingers.
Double knot the ends and tie it tight. Then Cut the loops
Make sure all the loops are cut. Trim the pom pom so that the ends are even and it’s more of a sphere.
Now begin sewing the pom pom onto the top of the beanie.
Double knot the ends on the inside and cut them close.
You can hide these ends in, but it’s not necessary.
