Draw a folded map in Aquarell: turn printed lines with the folds

Arrange four panels of a partly opened map, checking paper thickness, mountain and valley folds, and a route crossing panels.

A folded map combines three-dimensional paper with printed information. Establish four alternating panels before adding a fictional route and restrained terrain marks. This is neither a navigation map nor geographic-scale guidance; the aim is to make printed lines belong to the folded surface rather than float above it.

Begin with four blank panels

On an approximately 1800×1400 px landscape canvas, sketch four partly expanded accordion panels with coherent near/far widths. Establish folded top and bottom edges and joined corners on separate paper and print layers. Check blank-paper continuity before printed content; crossing a gap with a route cannot repair disconnected planes.

Alternate mountain and valley folds

Mark alternating raised and inward folds, allowing unequal opening angles and projected widths while preserving one sheet’s boundaries. Number panels temporarily, then hide marks. Vary orientation in a fence-like result or restore flatter planes and definite folds in a cloth-like one. Irregularity should not destroy the alternating structure.

Separate panels with light on one paper colour

Under upper-left light, use related warm and cooler beige-greys according to orientation rather than alternating pure white and black. Keep planes broadly flat and darkest values local to valleys. Reduce plastic-like colour jumps or increase useful plane separation when too flat. Resolve the unprinted sheet before visual information.

Suggest thickness selectively near the viewer

Show a very narrow near lower edge with occasional small wear, simplifying distant edges. Avoid four separate black frames around one sheet. Reduce wood-like thickness or restore opaque paper to a film-like result. Check the near edge continues coherently through corners before fine edge marks.

Project the route onto each panel

Plan a simple route and its crossing points off the map, then draw it panel by panel. Change projected direction at folds while joining at shared edges and compressing farther widths. Test without labels. Repair a floating-ribbon appearance through surface alignment, not a cast shadow: this is print, not a separate raised object.

Turn terrain and lettering with the same planes

Use one terrain patch and a few invented place names. Turn their edges and baselines with each panel; do not promise automatic perspective text. Hand-letter or use available controls, reducing labels when needed. Omit a misleading scale from fictional distances. Clear, limited information is better than false precision.

Keep valley shade compatible with printed information

Let printed routes darken with shaded paper while retaining useful contrast; they should not glow on the darkest panel. Keep valley darks narrow. Reduce valley area if routes fragment, or recheck plane values and shared edges when the sheet becomes four flat cards. Printing and illumination must coexist.

Test folds without the route

Hide print to inspect alternating folds, continuous lower edge and depth, then restore it to check joins. Review opening direction small and route seams close up. Repair paper structure when the blank version fails, or simplify equally dark grids when print flattens it. Retain both previews to distinguish the sources of problems.

Enlarge one fold corner

Study two adjacent panels and one crossing line at a changed opening angle. Projection changes but the line still joins at their fold. Temporarily distinguish panels in grey if colour distracts. Apply the successful relationship to one main fold at a time; complex terrain is unnecessary for testing whether print belongs to the surface.

Make a second opening-angle version

Keep blank, route and finished versions with editable print. Next, open the middle panels farther and rebuild corners, widths and route crossings without changing names or palette. Horizontal stretching is not a new fold configuration. Note the changed lettering baseline and label the result as fictional illustration, not a navigation resource.

This exercise uses public brush, colour, layer and saving capabilities. Form, materials and light are drawn manually; dimensions and palettes are suggestions. Check controls in the installed version. No step-by-step physical-device testing is claimed.
