Another solution for this is a notebook with removable pages, you can scribble all you want and if you decide later you don’t need that page in this notebook you can take it out (toss it, store it, or reorganize to a different notebook) and add fresh paper as needed.

It’s also handy to be able to reorder pages if you’re bouncing between purposes, and gives you the option to have a mix of papers if sometimes you want lined and other times dot grid or blank.

Yep im the same way. Tried lots of types, settled on the fabriano dot grid glued pages. Most of my pages are just this dirt style, but its also nice to sometimes rip out a page and these do so cleanly. Sometimes they fall apart... Thats okay, once i had a whole banker box full of notebooks the appeal of saving them all wore off. Now when theyre done theyre done.

All pages are removable.

I keep mine loose in a box
