Grave plots are generally three feet wide and six feet long. Most grave plots are arranged in rows. The very first thing when recording an historic graveyard is to identify the row arrangements. Be patient and let the patterns reveal themselves - we prefer to find the straightest row (often along a boundary wall) and start there. Then we number the memorials (using strips of masking tape with numbers stuck to the back of the memorials) and sketch the relative location of the memorials. With practice, surprisingly accurate plans can be drawn. We have been using A4 ruled pages for the drawings but Robin Turk has just designed a new template sheet for the plans.
