I have a bunch of different books that I play in- cutting, pasting, doodling, drawing and writing.
This is one I've had for a long time-it was a gift. It's actually a small size lined notebook that had a leather slipcover. It was very handsome, but I never used it...until I took the leather slip cover off, tore a bunch of pages out and starting gluing stuff in it.
I call it a "glue book" but technically, a glue book is put together with just scissors, paper and glue. I've done some doodling, lettering and outlining in this.
Another journal I'm working on is my Remains of the Day journal. I made the cover a couple of years ago but it's taken me some time to sew the pages together.
The pages are finally made, but I still want to sew some more "extras" on the pages.
A third book I've been having fun with is "Art Doodle Love" by Dawn DeVries Sokol.
It's a paperback book designed to be doodled in. The paper is nice and heavy, and the pages are full of fun backgrounds and prompts for what to doodle.
