The Original Digital Sketchbook Tree. As of Jan 1st 2020 I lost track of the order of the 1st Digital Sketchbook. Over time I’ll piece it together. And that is the function of this page. As the book branches we will make more pages. I plan on doing this over a long period of time alternating between the old book and the new book Digital Sketchbook 2020. Click the Thumbnails to watch and read about them.
