Copy your drawing. We're putting the pencils away now, so everything from here on out is permanent. That means if you make a disastrous mistake--or two, or three--as soon as you put the marker down on your paper, you won't be able to do much about it. By copying your drawing you'll have a backup if something goes wrong. The easiest way to do this is to use a photocopier and adjust the darkness setting so that the light pencil lines will show up on the copy. You can also try to trace the drawing onto another piece of paper, but this will be difficult because of the lightness of your drawing. If you do want to trace what you have, wait until after the next step or trace a photocopy.
