I wasn't looking for a new portable sketchbook when I found the one pictured in the photo below at San Clemente Art Supply Store. I have been content using Moleskine watercolor sketchbooks that I carry with me to sketch anywhere.
What made me stray from the Moleskine and buy this new sketchbook? I liked the sketchbooks size, it's light weight cover, its paper quality (strong enough for watercolor painting), and it's stitched binding so you can paint across the pages.
