Pencil sketch.

I am being greedy and drawing on both sides of the page in wonderful Delta sketchbook by Stillman & Birn, which I am carrying with me through the day. This time I went to medical office for a few minutes, auto shop to change breaks, spent few minutes waiting in the car near train station, wrote down the recipe for the hair mask, so my all day is drawn on this page in crumbling sketches on the top of each other.
Strong paper sustained multiple
washes. I want to find Faber-Castell water soluble pencil to add to my bunch. For a while I take with me in a pencil case few water soluble pencils and can't get enough of it.
