An integrally molded leaf-like decorative strip is provided for insertion in a U-shaped channel member. This strip is molded integrally in the form of a pair of half-base members joined together along a common edge by a living hinge about which said members may be folded. Further, integrally molded with at least one of said half-base members along an edge remote from the common hinged edge is a series of leaf-like protrusions extending away from the half-base member. When the two halves are folded about the living hinge and brought into abutment a decorative strip is formed which may be inserted in a supported upwardly facing U-shaped channel member, or otherwise utilized.
