I have filled one or more sketchbooks annually since around 1992. When I last counted in 2019, I found 81 volumes total, some of which are documented on this page. That means I fill approximately 3 sketchbooks a year. That average holds true, with some variation, of course. My Book of Errors, at over 500 pages, took me an entire year to fill. Some smaller tomes, such as the book I filled for The Sketchbook Project in Brooklyn, NY, went faster.
In undergraduate and graduate school, I began binding my own books. I deviated from this practice in the years afterwards due to time constraints and the breadth of my artistic interests, but I have returned to valuing binding my own books to create a sort of hybrid of sketchbook at artist book. I use up-cycled materials and prints for the interior folios and the cover.
I tend to favor coptic stitch and long stitch techniques, for their ability to lie flat, hold up to lots of abuse (I carry my books everywhere and have 2 children), look elegant, and allow me to easily use repurposed materials in their construction, including a variety of page sizes that do not have to be uniform. I recommend Keith Smith’s Binding Without Paste or Glue to anyone wishing to learn these stitches.
