This past month I participated in Sketchbook Skool (yes, that's spelled correctly), an online sketchbook class created by Danny Gregory and Koosje Koene. Over 6 weeks, both of those well-known sketchers, along with Prashant Miranda, Jane LaFazio, Roz Stendahl, and Tommy Kane generously shared their tips for sketchbook drawing. They are all fantastic, of course! And they all offer different approaches to this art. I've been following Danny Gregory ever since he published his inspiring book, "Everyday Matters." I came across Tommy Kane right after Danny and have several of his prints. I could slobber over all of them, but I'll let you discover them by yourself! Plus, to be honest, it's 1:41 a.m., and I'm tired. Here are their websites.
