Delivered today, my summer sketchbooks, and I’ve gone for five A5 landscape Pink Pigs. I’ve been working in 8-inch square and A5 portrait sketchbooks but I for me a landscape format works better for natural history, as you’re always in a landscape of some sort. My A6 landscape travel sketchbook can seem a bit cramped and A4 landscape can seem a bit too much to fill in one session but A5 landscape is right there in the ‘Goldilocks Zone’. Not too intimidating to aim at one page of natural history a day.
