ABSTRACT:
Spot markers for delineating areas used for athletic contests or games are configured as flat panels made of flexible material. Each panel includes a tongue and recess wherein the panel may be folded over and retained in a folded position by inserting the tongue into the recess. Each panel has a plurality of rectangular slots on opposite sides of a fold area into which extend rectangular flaps which are stiffened by stiffeners adhered thereto. When the markers are folded to form boundary markers, the flaps extend laterally to engage the ground so as to stabilize the boundary markers.
