Preface: I'm a terrible artist, this probably colours my approach to visual art in journals (i.e. I don't tend to do it). If I were a decent artist and drawing stuff each day, I'd be tempted either to keep a separate paper journal for sketching, or maybe to do sketches in something with removable/tear-out and scan them at the end of each day. If I just liked a more visual form of writing things down, I'd probably end up with something similar to the bullet journal link above. I do have a big (probably too big, really) Moleskine softcover book for when I'm jotting down ideas that can't be summed up accurately in plain text, but things tend to get lost in there quickly. I guess I just really like the ability to search for every entry I've written where I've mentioned flaming goats and have them all appear in less than a second, is all.
