I have many, many Moleskine notebooks...they are perfect for my varied needs.  I really like to use these large hardbound notebooks as my Commonplace books, because they are sturdy and the perfect size for recording the various pithy comments and quotations one always comes across, and do not want to forget.  These notebooks, together with the weekly planner and assorted cahiers, fit into my fauxdori very nicely, so they are always close to hand.
