When you think you have enough masking tape, rip it and flatten it down. Test to see if it is thick enough by sliding one of the comfort grips on. If it slides on too easily you will need more tape. You want the grip to have some resistance so that it will stay on when the hook is in use. I used 2 comfort grips per hook so that the entire handle up to the thumb rest was covered. I had enough to do 10 hooks from one package of comfort grips. Check out my new sparkly hooks!
