Prepare to Draw chapter 4
When you try to represent a more complex contour or form,
draw multiple straight lines to represent each section of the
shape that you have observed with your measuring tool.
You can repeat this process as many times as you feel is
necessary. It helps you to see the objects that you draw
more clearly. You will be surprised at how much easier it is
to record difficult shapes if you use this method. Feel free to
lightly draw these straight lines on your drawing to use as a
guide. You can also leave them on your drawing. Some artists,
such as Euan Uglow and his teacher William Coldstream, left
guidelines on their drawings or paintings in the form of lines
or tiny crosses. They felt no need to remove them, and, in
turn, these marks became a part of the work.
