Craftelier turquoise book cover ruler set

What this tool is for
Craftelier's turquoise cover layout set separates board position, hinge spacing and the corner cut. Use the L ruler to place a board with a consistent margin, then use the separate guide when you need the same gap on both sides of the spine. The kit is useful if your project calls for its documented 1.5 or 2 mm gap settings.

Fit and buying advice
The maker describes the L ruler as 2 cm wide. The separation guide has 1.5 and 2 mm positions. Those numbers describe different pieces and tasks. Dry-fit the book block in the case and check the gap with your covering material before using either spacer setting. Check the hinge gap with the book block dry-fitted in the case. If your case needs a different gap, choose a guide with that spacing.

Questions about this tool
Does the width of the L ruler set the hinge gap?
The L ruler helps position the board and its margin. The separate guide sets the hinge gap at one of the two documented positions.
What if my case needs a larger gap?
Use a guide with the required spacing, or measure and mark it before placing the boards. Check the dry fit with the actual book block.
How do I choose the corner allowance?
Test the corner guide with an offcut of the same board and cover material. Fold both edges to see how the covering meets at the corner.
