I keep a number of single sheet blank books folded so that I can always grab one and start drawing. I took one off the shelf a day or so ago. I had made some marks previously and decided to buff them out.
It was great to draw with these metallic inks. Each layer blocks out the previous. Density and pattern revealed by the overlays. This is the current state of the book. It may be finished. I'll know the next time I look.
