How to assemble
- Print all tiles at 100% scale in your browser print dialog.
- Trim along the inner guides where needed. Leave the overlap zones when assembling.
- Follow page labels such as A1, A2, B1 and the assembly order numbers.
- Join the first row left to right, then attach the next rows top to bottom.
- Use the overlap shading to know which edges sit under neighboring sheets.
For PDF export, this app tries to use the browser print engine or an optional built-in jsPDF loader if available. If direct PDF export is unavailable, use Print → Save as PDF.
