Wearingeul Reservoir Thread Note (B6) — a fountain-pen-friendly, lay-flat notebook you’ll actually want to use. Comes in three colors, which are specific to the ruling: Grey: Plain/Unruled Green: 4mm Grid-ruled Blue: 7mm Lined Wearingeul built the Thread Note around their Reservoir paper: a substantial 140gsm sheet with a smooth feel and just a hint of tooth (i.e., feedback), made to keep fountain pen ink crisp, controlled, and readable with minimal show-through. In pen testing, it plays nicely across the board (no drama: no feathering, no bleeding), which is exactly what you want when you’re switching inks/pens mid-page or writing with a wetter nib. The signature detail is the exposed thread binding, which lets the notebook open truly flat—perfect for journaling, ink logs, sketching, or making this your commonplace book without fighting the spine. The cover is clean, minimalist cardstock.
