Answer:
After you have just one loop on each finger, usually what i do is take the one loop on your pinkie finger and bring it up and over to be the top loop on your ring finger. Then take the bottom loop (the loop originally on that finger) and take it over to the middle finger. Take the bottom loop on your middle finger and put it on your index finger. Take the bottom loop on your index finger, take it over your finger and let go, keeping hold of your loop still on the finger. Take that loop off and cut the yarn from your wool ball and make sure it's long enough to reach your pinkie to your wrist. Now take that wool and put it through the loop and pull. It shrinks it slightly but not too much. I hope this helped :]
