I used this Fabriano sketchbook as a place to experiment with mixed media techniques. This was originally my planner/to-do list, so every page had writing on it that I covered up with paint or collaged scraps of paper. I'm really pleased with some of the pages!
I shared a video of this sketchbook earlier when it was still half-way done: Anti-perfectionist recycled art journal in progress.

Short video, no talking
