There is a hole in the fabric, allowing a tiny amount of light to shine through.
The fabric and stone floor and edge of the table are visible. The spirits for holding things together, for being traveled across, for keeping things separate, for sharpness can be reflected and copied, hundreds of times over. The metaphor is built, allowing travel, cutting between places, keeping the places separate, holding the target together, powered by further extra copying spirits. When the spirits begin to consistently complete the pattern without being pulled, the entirety of the collected and copied spirits are added to the pattern, with the mirror as the target, shifting and pulling.
The mirror is somewhere else.
