Since this would be a very large doodle, expect it to take a lot longer. The above images are work in progress' of the one I am currently doing.
Anything that is about the size of a standard notecard or slightly larger.
Medium and large one page doodle. Using black prisma pen. If asked, will do this in ball point (bic brand.)
A doodle that is on two pages or on a big page (example two and three). Will do in micron/ball point/or other fine tip pens.
