I grew up surrounded by paper!
My father was a graphic artist back in the day, and used to cart me around with him when he would visit print shops all over Boston. This was from the age of 5 to about 12(?) The printers would always give me free paper. Reams of paper, pads of paper, in all different colours, calendars, magazines, you name it.
I was fortunate that I always had something to draw on.
In fact, in my 20's, long after my father's death, I was still using that paper! And I never got sick from it...
