This everyday size one is perfect for jotting down quick ideas, sketches, or a few lines of poetry. If I'm doing rough drafts of poems or longer thought processes and go with a medium or full-sized journal.
I use Obsidian not only for my note taking but also to keep track of every book I have created and the details for it.
This is sounding more interesting and I'll definitely give it a look. Thanks for the recommendation.
