One of the things that I did myself is make a book, but a book as a piece of art both as a whole and what it contained. I used deckle edged art quality paper which I hand stitched into a binding and then made a cover that was quite tactile rather than 3D with motifs on it that you could feel but not see very well. That way it gave it a "hidden depth". The inside of the hard cover I just gave a professional finish to. The finished thing looked and felt otherworldly like you were picking up something esoteric and there was hidden meaning in it, which I suppose there was as it was an insight and documentary of what I was thinking. It documented a time and feeling for me.
You can get all you need for the binding part cheap on sites like Temu. The mesh for wrapping the pages and sewing to I used rolls of builders dry wall repair tape (that was such a find).
If it helps here is my introductory post on Hive. A few bits of art on Hive too

Everything I do is catharsis really. The quote by Picasso in the intro is as near as perfect for me.
