Artist Sketchbooks, March Gathering at the Gallery

Idea for this discussion?
A sharing of artist sketchbooks by the artists who use them!
It's likely the gathering will delve the joys, motivations, and challenges of keeping visual diaries and aspects of our relationship to the pursuit.
Could be very fun, both for those of us who keep sketchbooks, for those of us who contemplate the activity, and for those of us who are just curious.
