Marking Out Tennis Football and Other Pitches
It is a very tedious job to mark out tennis courts and football pitches if you do not posses an expensive machine for the purpose and you employ the ordinary hand method. The white lines can be made easily and well, however, if you construct a board like that shown in the illustration. It consists of two long strips of three plywood , with a space of 2 inches separating them.
All you do is to put the board down on the ground where the white line is to come and, you brush the whitewash on the grass seen through the opening. When one length is done, the board is lifted and placed in position for the next length. And so on, until all the lines are completed.
Give an eye to the underface of the contrivance and wipe it if any of the wash creeps on to it.
