A5 Sewing-Hole Marking Guide — 3, 5 & 7 Holes

Lay out three fixed sewing-hole patterns for a 210 mm A5 bookbinding fold. This 3D-printed guide has separate rows of 3, 5 and 7 marking holes.

• One black PETG marking guide, approximately 210 × 24 × 3 mm.
• Each pattern is centred along the length, with the outer hole centres 15 mm from each end. Centre-to-centre spacing is 90 mm for 3 holes, 45 mm for 5 holes and 30 mm for 7 holes.
• Choose a row by counting its holes. Use the small end notches to align that row with the fold, then mark through the holes with a fine pencil.
• Pencil, paper, awl and punching cradle are not included. Check marks before piercing and protect the work surface.
• The images are design renders; printed colour, dimensions and surface finish can vary.

Made to order. Allow 3–5 working days for production and packing, excluding courier transit.

This is a fixed-pattern marking aid; it does not punch holes. Keep away from excessive heat.
