Symmetric tool

Print the sheet at 100% / Actual Size, then lay the tool flat on it.
Tool bigger than the grid? That's fine. It can run past the grid or off the paper. Just keep it off the 4 corner markers and fully in the photo.
Hold the camera level, straight above the sheet, with the flash on.
On iPhone, turn on Settings › Camera › Grid, then line up the two crosshairs in the Camera app before you shoot.
Keep all 4 corner markers uncovered and in the frame.
