Abstract: A decorative border structure (100) is disclosed. The decorative border structure (100) includes a plurality of border picket assemblies (102), each consisting of a picket portion (108) and a stake (118). Snap assemblages (126) are located on opposing sides of the picket portion (108) of each of the border picket assemblies (102). The snap assemblages (126) are adapted to releasably and pivotably interconnect with trim spacers (104) which, in turn, pivotably and releasably interconnect with adjacent ones of the border picket assemblies (102). The relative structures of the trim spacers (104) and the snap assemblages (126) facilitate assembly of the decorative border structure (100) with curvature, and also permit use of the decorative border structure (100) on uneven terrain or with terrain of substantial inclinations and declinations.
