NOTES FROM THE WORKBENCH
A sleeve for a handmade notebook
A notebook sleeve depends on the closed book's thickness, its cover corners and the amount of spine you want to show.

Measure the notebook closed
Close the notebook in its normal resting position, including any elastic band, folded cover flap or attached pocket. Measure the largest width and depth through which the sleeve must slide. A soft book may change thickness when squeezed, so avoid using a compressed measurement as the only reference.
Sleeve length is a different decision: it is the amount of the notebook you want covered along its long axis. Leaving a portion exposed can help with removal and make the notebook's identity visible.
Use the opening estimate transparently
For an illustrative 60 × 20 mm cross-section, 0.50 mm per-side clearance produces a 61 × 21 mm inside opening. With 0.30 mm material, the neutral-plane estimate gives fold spans of 61.3 × 21.3 mm.
That example illustrates the calculation rather than prescribing a notebook size. Measure your own cover and select an allowance that survives a trial in your chosen material.
Place the seam with the front in mind
Wrap a plain strip around the closed notebook and mark the intended front. Follow the panel order to see where the seam will sit. A seam on the underside may be less conspicuous, but its inner overlap can still catch a corner.
Score the long folds, dry-wrap and check that the band is square before gluing. Keep adhesive inside the tab and avoid a raised bead along the insertion path.
Test movement after drying
Try the sleeve from both ends after the seam has settled. Check whether a cover corner catches and whether the band is loose enough to remove without scraping the book. A little flexibility in the cover can conceal a sleeve that is actually too tight.
Save a named project and note the paper. The sleeve has open ends; it is a presentation wrap and should not be described as a closed protective shipping case.
