Using a fork allows you to make pom poms quickly and evenly sized.
Lay the end of the yarn across the fork tines, holding it in place with your thumb. Begin wrapping the yarn around the fork.
Continue wrapping the yarn around. The more you wrap it, the fuller the pom pom will be.
Once you are done wrapping, cut it free of the skein.
Cut a a piece of yarn, approximately 6 inches long. Poke one end in between the middle tines, below the wrapped yarn. Bring the other end in between the tines at the top. Bring the ends together and tie a very tight knot.
Remove the pom pom from the fork. Bring the yarn ends around and tie them around the middle again.
Using a pair of scissors, begin snipping through the loops of the pom pom. Cut of the tied ends. If necessary, trim any long ends so that it has a round appearance.
Knifty Knitter pom maker. This is less than 5 dollars and comes with three sizes for you to make pom poms with. I made medium ones. Also something I had fun with, I took one color and wound it around the middle, then wound another color across whole thing.
