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 horizontal line equally dividing the top half of the figure. 4) Draw a horizontal line equally dividing the bottom half of the figure. 5) Now our grid consists of four identical vertical segments. Each of these segments is divided in half by horizontal lines.
