I need a new sketchbook and want to try one of the Stillman and Birn but can’t decide which series. They sent me a little pack of postcard sized paper samples. This is on the Beta series paper. I like it but even though I do use watercolor (mostly improperly) in my sketchbooks, I don’t tend to use the ones I already have with watercolor paper in them. I’m not a watercolor artist, I just use it to add a little color to my sketches. So maybe the Epsilon series would suit me better? Or one of the others? I’d love to hear opinions!
