GRID STEP. You can print out the base construction lines and start drawing on tracing paper or you can draw the grid layout yourself using the following steps.
1) Draw a rectangle that will define the conditional proportions and boundaries of the chosen drawing. 2) From the middle of the rectangle, draw one vertical and one horizontal line equally dividing the shape. 3) Draw a vertical line in the middle of the left half of the figure. 4) Draw a vertical line in the middle of the right half of the figure. 5) Now the grid consists of four identical horizontal segments. Each of these segments is divided in half by vertical lines.
