I found some pieces of tissue paper and tracing paper and used them to make drawings over the top of collages. This has a nice effect, like I'm adding a new dimension to the pages, and making the drawings seem a little ghostly. It kinda reminds me of how thoughts work inside our heads. We don't think in a linear pattern, it's more like thoughts and ideas and imagined scenarios pile on top of each other, just like a collage. We can see some thoughts through others, like they're layered in transparent sections and overlapping - just like these pages. And since my goal for this book is to mimic the inside of my head, that seems like quite a nice thematic overlap.
