How to use

Use the notebook as a sketchbook, planning book or journal by opening it flat and working across the full A4 sheet area. For drawing, start with light pencil sketches and then refine with ink or marker where appropriate; allow ink to dry before closing the book to avoid transfer. For notes and diagrams, use the blank format to create custom layouts, grids or templates directly on the page. Store the notebook on a flat surface or upright on a shelf to maintain the hardcover shape and protect pages from bending.

Recommendations

For best results, test pens and markers on a corner page to check ink bleed-through. Use light to medium-weight markers or fountain pens with appropriate ink to avoid excessive show-through. Keep the notebook dry and store it away from direct sunlight to preserve the cover color and paper quality.
