9d the first elastic band 18 a is positioned to loop around each of the second and third elastic bands 18 b 18 c and is not supported directly by the posts 28 a b an additional elastic band 18 d is then added above the second and third elastic bands 18 b 18 c such that the second elastic band 18 b is now the lower most elastic band as is shown in fig9 e the lower most elastic band 18 b is then grasped with the hook tool 14 fig9 f by extending the hook tool 14 into the access slot 38 and grasping ends of the elastic band in sequence pulling the ends away from the corresponding post fig9 g and looping each end over onto the and around the other links supported between the first and second posts as is shown in fig9 h an additional link is added above the two remaining links 18 c 18 d across the two posts 28 a b as is shown in fig9 i and the process shown in fig9 f through 9h is repeated with additional links to grow the length of the linked structure as is shown in fig9 j and 9k until a desire length or number of links are connected to each other as is illustrated in fig9 l once the desired length.
