About 10 years ago I made a conscious effort to start using a sketchbook on a regular basis. My plan was to draw often, on both sides of the pages, and not treat every drawing as a masterpiece. As well I swore to not tear out a page - no matter how bad the sketch turned out (many a page begs to be torn out - trust me). I started with an 8 1/5" X 11" - 216 page Canson basic hard bound sketchbook and still use them today. Why am I telling you this? Well I just finished book #9 - that's 432 pages of sketchbook X 9 books = 3888 pages!!! Hmmm I wonder how many pencils were used? Oh well on to #10.
