The soft cover edition is somewhat similar to the sewn boards binding, in that a bi-folium of 80# Speckletone Oatmeal cover is smythe-sewn as a part of the text block, front & back. The 100# Speckletone Brick Red cover wraps fully around the book all the way in to the gutter, and the Oatmeal cover adheres at the fore-edge, creating four layers of cover paper on both sides, resulting in a book that is both substantial and flexible.
