Diolch Owain. Thanks for the suggestion, perhaps some might like this minimalist approach. I’m aware of the history of the hipster PDA and even had one for a while back in the day. Ultimately I wanted something more easily slipped in and out of pockets, so rubber bands were also out from the start for me. I ultimately took the book binding glue route: https://boffosocko.com/2022/12/05/a-notepad-for-my-zettelkasten/ So far, it’s working relatively well.
