Once you have all your supplies cast on 14 stitches (you can pick the color of yarn). Using straight knitting, knit about 20 rows. Use a coffee mug to double check that it's going to fit (:.Sew the ends to together so you have a sleeve. Now get ready to make the pom pom :D.
Take your piece of cardboard,your compass and draw a circle about 2inches in diameter then in the middle of the circle make a smaller one about 2cm in diameter now cut out that smaller circle.
Place the rings together. The idea now is to wind the wool around the rings. Cut the wool into manageable lengths around 6 feet. Keep doing this until the cardboard is covered, you don't need to tie any knots just make sure the ends aren't facing the middle.
Next take your scissors start snipping away at the edges until you can see the cardboard. This is the hard part. Take a piece of yarn and tie it tightly around the middle. Remove the cardboard cut it if you have to. Trim any long threads so your pom pom is neat & tidy. Attach your pom pom to the sleeve using a darning needle.
