Sketching with triangular pencil.

I walked today on snowy roads, my car still stuck in snow.
I took the lightest bag with me because I want to  draw.  (sorry for the poem, it was just too funny and rhythmic).
With minimum drawing stuff, only 15 pens and pencils in my orange pencil case and brown book, hoping that today would be long waiting, so I can sketch. So here I used this interesting pencil-ruler and touch of white pen.

It was not long waiting at all but still got few sketches and headache.
