STEP 2

After scanning the image, I bring it into Adobe
Illustrator.  I create a layer titled "Reference"
that the blue line art is placed on.  I lock the
layer so I can't edit it, and I make it about 50%
lighter than the original scan.  I do this so I can
still see the image, but it's not distractingly dark
when zoomed in to work on the next part.

I then create a new layer for my line art, and use
the brush tool to essentially trace my scanned
line art.  I tweak the art in places as I go if I
didn't like a certain area upon closer inspection.
