1. A fastening system includes a straight pin having a cap end, a shank and a pointed end; a planar border having a base and two integrally formed substantially parallel planar flexible peripheral legs of like length, distal ends of each of the legs having apertures proportioned for slidable receipt of the shank of the straight pin; and an elongate securement leg integrally dependant from the base in a direction of the distal ends of the flexible legs, a distal end of the securement leg including a female surface press-fittably complemental about the pointed end of the straight pin. The pin may be inserted through the apertures when they are aligned with each other, and then held by the female surface to enable securement of a planar peripheral legs to each other.
