Both serious artists and casual doodlers can use the handsome sketchbooks, now offered in seven colors, four sizes, and with the options of lizard finish or Kivar covers and a sewn or spiral wire-o binding. Many choose the popular large format for sketching outdoors or for toting to art class. Others like to toss the smaller sizes into a purse or backpack. The archival-quality, vellum-finish paper is especially appealing to artists. It will not yellow with time, ensuring the preservation of their drawings, and its smooth surface readily accepts any drawing medium. The spiral-bound version opens flat. All the covers have a leatherlike finish but are actually tough and waterproof.
