Big drawings are eye catching and bold, but creating one may seem like a daunting task. The best way to draw a big picture is to make several sketches of it on a smaller scale. Doing this familiarizes you with the image. Once the small drawing is perfected, transfer the smaller image to the larger paper proportionally. Making the drawing proportionally bigger can be a little tricky because it requires precise calculation. When you have the right measurements for each of the lines, the execution of the drawing is simple.
