01
Interlacing is a useful organising idea
Weave suggests that separate strands retain a role within a larger whole. Applied to maps, that idea can encourage a design in which layers remain identifiable after combination. Applied to textiles, it can point toward the actual relationship between crossing elements. TopoWeave can support either interpretation, but the introduction should show which one is intended. A small labelled example gives the name substance and helps prevent a decorative crossing line from being mistaken for a technical description of how a material or map is constructed.
02
Give each layer a distinct job
A layer becomes easier to understand when it represents one stated kind of information. In the mask exercise, A and B simply indicate two sets of marked cells. In a more developed project, a layer might represent a route or a region category. Mixing both in one unexplained colour can create ambiguity. A useful TopoWeave presentation could list the layer name, what a mark means and its source. That concise key gives readers a way to interpret the final composition and to notice when two layers use incompatible definitions.
03
Decide what overlap should communicate
When two marked regions coincide, the combined view can show either that at least one layer is present or that both are present. Those are distinct questions. A visual identity built around layering benefits from keeping the distinction explicit. The page can use separate views for union and intersection, with a caption explaining each operation. This lets the same source material support different readings without pretending that one composite image answers every question. It also encourages designers to choose an operation before choosing its decorative appearance.
