posca lines

whats the easiest way to do a curved edge line mid board on edge of the design? the design is a rail line from end to end with a curved line to the centre from each end (dont know if that is clear) but my spray line is a bit wobbly so i want to cover the edge, i used a cheater tool for the rail line. thanks
