i think i thought of something
quite intelligent.
for once.
when you are shading something,
the blacker, the darker.
right?

but what if, its
white chalk agaisnt black paper?
then when you shade, you white-en it.
but technically, youre adding more white parts.
so you shd be lightening it, instead of shading it?

OKAY ANYBODY UNDERSTAND?
hee.
this question just got me thinking.
for a really longgg time.

mmm wadyou say?
that you only meant well
of course you did
of course it is -imogen (:
