Ask HN: What your favorite sketchbook/notebook to store your brain dumps?

I am having an unexpected difficulty to find a good notebook/sketchbook to bring along with me and where to "brainstorm with myself" during my work as a software developer and my personal life.

As I enjoy using application with good UI and great UX, I want to find a notebook where I can store differents months of free thoughts (it seems that asking for more than 40/60 pages is asking a lot) and that feels good.

Would like to know if some of the people here have some suggestion, I am interested in not too small formats (perfect would be A5).

I just have a stream-of-consciousness text file where I type anything that's on my mind, including ideas. Main downside is that I can't scribble on it.

Moleskine would be default choice for me.

I'd go to any art supplies store and look in the stationery section, you'll find lots of options in there.

Lately I bought some Pantone notepads, they come in several sizes, sturdy and have dotted guides.

But 99% of the time I just use cheap 99¢ notebooks.

Mine too! Moleskine classic hardcover for me
