Nature Sketch is the go-to artist heavyweight paper that accepts pencil, pen, ink, markers, pastels and oil pastels, charcoal, watercolor pencils, light washes and acrylic. The sketchbook contains 50 pages of 130 lb (211 g/m2), 25% cotton, cream-colored paper with a medium tooth surface. Each sheet has a rough vellum front with a smoother surface back. The elegant foil-stamped front cover is a hard, thick cardstock cover. The pages are bound with a double pewter metal spiral binding that resists warp and protects your work.
