Doodles can be called mindless drawing.  It’s one of the last places drawing still exists in a person who gave up on art long ago.  A place where one line can still follow another without plan.*
Lynda Barry

Doodling is great for
not trying to be tidy or
accurate or to
impress someone –
In fact, it can be used to
break the habit of these very things.

You are welcome to print this off and
