The grid method of drawing lets you precisely reproduce an image. It can also be used to make a reproduced image larger or smaller while still maintaining its proper proportions. This method is performed by drawing an even grid over a reference picture then drawing the picture square by square on another blank grid of equal proportions. Graph paper is useful when using the grid method because it features printed lines that help you measure out squares.
Use the ruler to draw a grid across the length and the width of your reference picture of a heart. This will break the heart image down into a series of smaller images.
Copy the grid on the reference photo onto the graph paper using the pencil and ruler. Use the printed grid lines on the paper as a reference. The squares you draw must be evenly spaced and perfectly square. The squares may be as large or small as you choose, but they must be geometrically correct and all the same size so the heart you draw will not be distorted.
Draw your heart. Focus on one square of the printed picture and draw the contents of that square into its matching position on the graph paper. Do this for every square of the grid. Draw exactly what you see in each square, rather than what you think the heart is supposed to look like. Your finished drawing will be extremely close, if not exactly the same, as the reference picture.
Use the eraser to eliminate the grid lines you drew on the graph paper. Touch up any areas that require it, but do not overcorrect your work. Your heart is complete.
