Keeping a journal for origami isn't about making it look pretty. It's about having a record when you forget how you made something.
I started a journal about six years ago because I kept making the same model three or four different ways and couldn't tell which version was better. The first time I ran into that problem, I had spent two hours collapsing a model only to realize I'd forgotten whether I did the preliminary base before or after the petal fold. It's not glamorous, but it stopped happening after I started writing things down. Now I use one for tracking successful models, another for failed attempts, and a third for diagram studies. The basic method is straightforward. You pick a notebook. Buy one. Don't overthink it. I use a A5 hardbound notebook with 120gsm paper. Thinner paper gets ruined by wet glue when you're working through water origami models. That's one thing I learned the hard way after three notebooks collapsed at the spine from wet pages. Each page should have the same structure. At the top, write the model name, source, and date. Under that, the paper type and size you used. Then the fold sequence broken into numbered steps with short descriptions. Don't write paragraphs. Write fragments. "Sink fold left petal" is enough. Three years in, I can read my own fragments perfectly fine. You won't be able to read elaborate descriptions either, so don't bother.
The part most people skip is the margin notes. Keep a column on the right side of each page for observations. Things like "this step is tight on 15cm paper" or "reversed the reverse fold here and it held better." Those notes end up being more useful than the fold sequence itself. I've found maybe twelve models where the margin note saved me from repeating a mistake I'd already made once before. Diagrams matter more than you'd think. You don't need perfect diagrams. I draw mine freehand with a fine pen. But if you're trying to figure out a complex sequence months later, a rough diagram with arrows showing direction of folds will help you reconstruct it in about ten minutes. Without one, you'll spend twenty minutes trying to remember which way each valley fold went. Here's something that catches a lot of people off guard. Number your pages and keep an index on the first two pages. When you've got fifty models logged and someone asks you about a specific technique, flipping through random pages wastes time. The index takes three minutes to set up and saves you fifteen every time you search. That math alone makes it worth doing.
One specific problem I hit early on involved wet gluing. I was documenting a water bubble technique and accidentally got water on the page next to where I was writing. The ink bled and the paper warped. I switched to archival ink pens and started doing all wet-glue documentation after the model was complete rather than during. It added maybe five minutes per model but eliminated about eighty percent of the damage I was causing to my own records. For the diagram-heavy models, I photograph each step with my phone and paste the prints into the journal. The adhesive from cheap photo tape yellows over time. I switched to acid-free photo corners and it made a noticeable difference in how the pages age. The corners are slower to use but a journal that stays flat for years is worth the extra minute per photo. Another thing nobody tells you. Don't use the journal as a scratch pad for experimental folds while you're still figuring the model out. Keep a separate notebook for that. Once you know how the model works, transfer the clean version to your main journal. Mixing the two creates confusion. I found this out after three months of trying to trace a model back through my own notes and realizing I couldn't tell which version was the final one.

What the system actually gives you
You get a searchable record of your work. Six months from now, you'll remember roughly what you did but not the exact sequence. A proper journal entry lets you reproduce a model in about the same time as the first attempt, sometimes faster because you've already figured out the hard parts. You also build a personal library of what works and what doesn't. After a year of journaling, you start noticing patterns. Certain paper weights behave predictably with certain fold sequences. Certain bases fail consistently at a specific step depending on your folding style. These observations are invisible unless you're tracking them. There's a third benefit that shows up later. When you teach or share your work, having a clean reference makes the explanation faster. I've watched people try to explain a model from memory and spend ten minutes reconstructing it verbally. With a journal entry to reference, it takes two minutes. The difference is just having the information in front of you.
Paper and tool specifics
120gsm is the sweet spot for most people. Heavier paper holds ink better and survives repeated handling. Lighter paper is fine for rough drafts but falls apart fast. I've seen people use 80gsm notebooks for daily tracking and replace them every few months. That's fine if you don't mind the cost. I'd rather spend more upfront on better paper. Ink type matters more than the notebook itself. Gel pens smear on glossy pages. Ballpoint pens skip on recycled paper. I use a 0.38mm archival gel pen on matte pages. It dries fast and doesn't bleed. The brand doesn't matter much as long as it's archival. Cheap pens fade or bleed within a year. For diagrams, a mechanical pencil works best for rough sketches. Switch to a fine liner when you're ready to finalize the entry. Pencil smudges are annoying in a bound notebook where you can't flip pages freely without touching everything else.
Where this approach breaks down
Journaling every model is time-consuming. A complex model might take twenty minutes to document properly. If you're folding dozens of models a month, that adds up. I keep a separate "quick log" for simple or practice models where I only write the model name, paper size, and date. The full journal is reserved for models I expect to fold again or that took more than an hour to complete. Hand-drawn diagrams have limits. Some models have so many steps that even rough diagrams become illegible after a few months. For those, photographing the final folded state and pasting the image into the journal with a note about key steps is faster and clearer. I do both. The diagrams for moderate complexity models and photos for the really dense ones. Digital alternatives exist. Apps like Origami Journal or Foldify let you log models digitally with photos and diagrams. They're faster for entry and easier to search. But they require a device and power. A physical notebook works in any lighting, doesn't need charging, and doesn't become obsolete when software updates. I use both. The physical journal for detailed reference work and the app for quick logging while I'm actively folding.
The biggest limitation is consistency. Most people start strong and drop the habit after two or three months. The solution isn't to try harder. It's to make the system smaller. One page per model maximum. No decorative elements. Just the facts you actually need when you pick the model up again. Perfection kills consistency. Adequate consistency keeps the journal alive.
