– Mark the Line Start Positions – with the tape measure still on the ground, mark the
line start positions based on the line spacings (Figure 7-5). Usually flags or paint work for

every so often, in case you forget which line you’re on.

– Mark the End Positions – if you are doing a forward only grid, it is recommended to
mark the end positions (Figure 7-6). You will need to aim for something to make sure your line
is straight.
