Small luxuries make a big difference. Never had a Mnemosyne notebook before but I’ve heard good things.
@jeremycherfas the Minemosyne notebooks I have are some of my favorite especially for use with fountain pens.
@klandwehr Oh excellent. They're a little larger than the sprial bound Field Notes 56-week planner that they are replacing, A5 rather than 12 x 19 cm, but I'm looking forward to using them.
