One of the reasons I like to teach is because the school is located in a nice beach town (Nabeul) an hour from home. Lots of things to sketch, like the rooftops seen from my classroom.
And now, I can sit in the backseat and sketch other passengers--motion sickness conquered! I'm getting kind of wild with the cross-hatching. It may degenerate into scribbling soon!
I find the size of this small journal (4"x6") to be very convenient. Yesterday I took my larger handmade journal to a restaurant and found it difficult to work with in a cramped space (well, duh!).
Ballpoint pen with Prismacolor pencils added later. It actually takes longer to add the color than to do the sketching.
