Abstract: An adjustable boundary layout and apparatus for outlining shapes and figures or a playing field of any dimension, made up a plurality of detachably connected flexible cords (10) attached by connectors (14) and assembled to the shape desired at the time of usage. The boundaries are stored and transported on a spool (18) or hook (55). The necessary number of cords can be unwound or rolled off spool and detached at the end of any cord. Cords and connectors can be arranged to form endless loops and can intersect through the use of various connectors with multiple joints. Connectors with cross-cut holes (15) are used to create a point of intersection at any point along the cords. Any number of separate boundary demarcations can be formed of any dimensions and any distance apart. In a preferred embodiment of the playing field, individual boundary demarcations of varying sizes depending on skill level and space limitations are formed for each player.
