Each chain link is punched out of a plastic sheet. The link has a closed form with a central opening and is divided on a line at one end of the opening. The link ends at the dividing line have interengaging shapes preventing separation as long as the link ends remain in the same plane. The plastic material can be flexed to spread the link laterally of the faces in joining one link to another. A slot in each link at the opposite end from its dividing line receives an adjacent link to hold the interlocking ends thereof in the same plane to thus prevent separation. The links are variously shaped to achieve different decorative effects.
