The method according to the present invention includes applying indicia to an element adapted to be located within a see-through material. The method comprises the steps of providing a bladder for locating within the see-through material and applying a first set of indicia on a first side surface of the bladder such that the indicia is visible when the bladder is viewed from a first side. The method also includes applying a second set of indicia on a second side surface of the bladder such that the second indicia set is visible when the bladder is viewed from the first side.
