Designed for Coptic stitch bookbinding technique

Workable area is 8.5", perfect for Letter (8.5"x11") sheets turned sideways, markings are imperial with 0.25" (6.35mm) spacing on center of each 0.13" (3.3mm) hole.

Markings are recessed enough to be distinctive but can always dab some paint into the markings and wipe across the top with a credit card for a professional, contrasting effect.
