drawn in light pencil to the required height. The vertical lines are then drawn to the required widths of each letter-and the space between the letters. The ratio of the height to the width of all letters is usually 4:3-except for 'M' and 'W' which are about square, and for 'I' which is only a single line wide. As a guide for the letters like 'B', 'E', 'H' and 'S' which have cross- members, draw another horizontal line midway between the top and bottom. The space between letters is not always equal. The difficult ones are letters like 'A', 'J', 'P' and 'T' which should be spaced against other letters to create a balanced visual appearance. This is a matter of eye judgment, but the illustration below may assist in solving the spacing.

When the completed letters are dry, erase the pencilled construction lines. A few other points about lettering are worth bearing in mind: for ease of drawing and legibility, use only simple block letters; the width and boldness of the letters are as important as the overall size of the letters for legibility. colour makes for impact and interest; test the lettering at the distance your audience will have to read it.
