Lay Over
Lay each layer over the last; keep each whole; read the stack.
Three tracings of one site, read as one.
Seen in Ian McHarg, Design with Nature, 1969
Try it on your work
Draw three things about one object on three pieces of tracing paper: its outline, its shadows, its seams. Lay them on top of each other and look. Stop there; do not copy them onto one page.
Write three lists about one place on three pieces of tracing paper: sounds, colours, names. Stack them and read down through all three. Stop there; do not combine them into one list.
Three people each mark the same floor plan on their own piece of tracing paper: where they would sit, where they would not go, where they would meet. Stack the three and read them together. Stop there; nobody changes their own layer.
How it has been used
Lay one thing over another on the same ground and keep each whole: the tracing over the plan, the transparent map over the site, the painted figure on celluloid over the background. Read the stack, and lift a layer off when you need to. The move forbids merging: no layer is redrawn into another.
