Well after moving the extra material back and forth accross the liner my son made a good suggestion. He said to oonly pull half the material otherwise I would just be moving the problem. Then after splitting it bewtween 2 sections we halved it again and kept doing that until we spread the excess out enough to hook it in all the way around. Hopefuly it holds. So far it is as tight as a drum thanks to all the info I rcvd here. will keep all that posted hopefully a happy ending is near.
