In 2020-2021, I participated in The Sketchbook Project vol. 18. The title of my book was "Illustrated Dream Journal", and it was a compilation of illustrations based on snippets from various dream journals I had kept through the years. When I finished it in 2021, I sent it off to be housed at the Brooklyn Art Library (along with over 50,000 other sketchbooks). Unfortunately, in 2022 a fire destroyed about half of the collection while en route to their new home in Florida. The Brooklyn Art Library shuttered shortly thereafter. You can read more about it here.
Though my book was destroyed, I did have the wherewithal to scan it for my own records prior to sending it off.
Below is a video flip-through of the sketchbook.
