It is best to have a schematic or a sketch of the proposed putting green and its location. This will allow for the installation process to be more efficient especially when it comes to the hole/cup placement. When the location is established, I recommend marking the furthest points at the exterior edge of the entire putting green, including fringe. This will create boundaries when establishing the putting green surface, fringe or desired synthetic turf collar.
When the outside boundary lines are established, paint out a rough outline to where the entire putting green will fit, including fringe, collars, sand traps, grass traps, etc.
Locate, mark and install the putting green cups.
