Open up your pom pom maker so it makes an 'S' shape. Start wrapping your wool around the top part of the S (the more wool you wrap, the fluffier the pom pom). Once the top part of the 'S' is covered in wrapped wool, close this section and start wrapping the wool around the second 'S' section. Once finished, close the second part of the pom pom maker and cut the thread to your ball of wool. With a sharp pair of scissors, cut between the middle of the wrapped wool where the join of the pom pom maker is. Take an extra piece of wool and wrap it around the join of the pom pom maker and pull it tight into a knot, so your pom pom wool pieces are secure. Unclasp of the green 'S' shapes of the pom pom maker and pull the pom pom maker apart in the middle. Pull out your pom pom and reshape it and trim it if needed.
