First Journal
Most beginner advice about first journal comes in the form of fixed rules — do exactly this for exactly this long, then stop. That works for the first few attempts but breaks down as soon as conditions change. First Journal is more usefully understood as a set of relationships: what is happening, what you want to happen, and the small adjustment that brings the two closer.
A practical way in: take whatever you currently do for first journal and try one experiment. Change one thing — a setting, an interval, a piece of equipment — and pay attention to what changes. Two weeks of small experiments will tell you more about first journal than any single article. The articles here can offer a starting point; the rest is yours to discover by binding.
None of this is meant as the last word. bookbinding is a hobby in which experience reliably outperforms instruction, and the only way to develop that experience is to keep measuring. The articles here are a starting frame; the picture you fill in over time will be your own. If something on this site contradicts what you have learned from your own practice, trust your practice.
