>>1003I try to define notebooks related to topics (say: computers, cooking, other hobbies) that matter to me, and try to put organized notes about what I learn and do in relation to this topic.
to the op:
I typically use fountain pens. Got used to them in school and just havent quit. Generally use medium nibs but have been getting curious to try some good fine nibs eventually.
As a kid I preffered blank paper for everything, and I think I still sometimes do. But lately have been drifting more to lined for some purposes that are rather text heavy.
