I picked up a Midori Traveler’s Notebook a month or so ago and have thoroughly enjoyed it. The leather is fantastic; the customizability is great. I carry it daily and try to maintain a logbook (facts more than feelings).
In addition, I purchased JetPens’ brush pen sampler. It is taking some time to get a feel for how each behaves, but I really enjoy the line variation I can achieve. If I can get faster while maintaining quality, I will add one to my sketchnoting arsenal.
