The thread stitching makes a very good impression and also the hardcover tells me of its power to, but it is difficult to write in something in the book. The cover is so stable that it has to be pressed vigorously with each new open page in order to generate a flat writing surface. In particular, the even-numbered pages (left) are otherwise hard to fill, at least for me as a right-handed. Since bringing with bookmark, numbered or detachable sheets, Auskleber for archiving or storage bag in the book very little.
