Lately, as a sketchbook, I've been using an omnibus collection of four Anne Tyler novels I bought used for a penny (plus $3.99 shipping and handling, alas) on Amazon. I draw on the pages after I've read them. Since I'm carrying the book around all the time it's convenient and economical to draw in it, too. I like the texture and complexity the typeface adds to the drawings. The first two novels in the collection--"Dinner at the Homesick Restaurant" and "Morgan's Passing"--are terrific, by the way.
