The Restorer Sigil

1. Print at 100% scale (no "fit to page"). The black square should measure 4.4cm.

2. Cut out a lid disc and stick it flat on top of a tin can. Matte paper beats glossy: no glare.

3. In dim rooms, keep the can within an arm's length. The scanner switches to night-vision on its own.

No printer? Open this page on a second screen. A lit display is a great marker in the dark. The stage card works without a can.
