Arrange side curtains, a top valance and stage floor through tension, overlap and values that preserve a focal opening.

Theatre-curtain folds respond to suspension and side gathering, not merely parallel vertical lines. Paint an empty fictional stage with side curtains and a top valance framing its opening. Establish the space before cloth detail. The central negative space is designed structure, not leftover blank area.

## Design the central opening first

Use an approximately 1900×1400 px canvas and block in opening, floor and side-curtain areas. A half-width opening is a starting point, not a rule; unequal curtains may still frame a clear view. Separate layers and test three grey masses before folds. Correct the area balance rather than filling the stage with props.

## Give floor and rear wall a coherent space

Keep rear wall quiet and floor a related different value, using a few faint depth guides. Align the wall–floor boundary with the opening, and make the floor wider at the front, narrowing toward the back. Place curtain feet nearer the viewer. Add separation cues to paper-cutout scenery or reduce exaggerated perspective when it overwhelms framing. Save this fold-free stage to check whether later cloth marks flatten the space.

## Let gathering points determine side-curtain flow

Give each side a gathering point below mid-height: upper cloth converges toward it and lower cloth spreads downward. Establish three main fold groups with tighter spacing near the tie. Avoid identical vertical tubes, waterfall-like uncollected cloth or rigid fan rays, preserving broad soft turns under coherent tension.

## Build the valance from hanging arcs

Hang the top valance in broad arcs between a few attachment points, gathering smaller folds there. Its forces differ from side curtains; do not rotate vertical folds unchanged. Occlude side-curtain tops. Soften sawtooth corners or board-like thick edges, establishing a suspended shape rather than a pasted coloured stripe.

## Group cloth values by main folds

Use muted dark red or blue-violet under upper-left light, grouping broad raised and recessed planes. Reserve deepest darks for ties and overlaps. Merge sausage-like isolated folds or add a few broad turns to flat paper-like cloth, rather than numerous dark lines. Values first explain one material’s orientation and light.

## Show selected hems and turned edges

Give a selected inner curtain edge a narrow turned face of varying width. Keep optional trim subordinate. Suggest a little pooling at the floor without repeated pointed triangles. Establish the turn’s origin and occlusion, reducing a detached scarf-like strip or clarifying one lost section instead of outlining the entire edge.

## Prioritise the framed space over fold detail

Keep the central backdrop simple rather than adding figures or equipment. Quiet bright corner texture that competes with the opening. The centre need not be white; area and edges also guide attention. Judge the thumbnail before selecting detailed fold groups, allowing peripheral simplification rather than treating quiet space as unfinished.

## Use shadows to separate curtains from backdrop

Use broader softer cast shadows toward the rear and small deeper floor contacts, with restrained valance shade. Restore spatial relationships and floor in a sticker-like stage rather than thickening edges. Review framing normally, opening ratio small and stray lines close up. Shadows explain distance but cannot repair impossible suspension.

## Test without texture and with one side hidden

Hide fine texture to test hanging structure, then hide one side to inspect the other’s forces independently. Symmetry alone should not create curtain identity. Repair one side in a copy before restoring the whole. Record a useful main fold and a dispensable line for future scenes rather than beginning by covering every surface.

## Keep the framing and vary opening width

Keep spatial block-in, principal folds and finished versions with separate curtains. Next, gather only the left side tighter, rebuilding fold density, edge and pooling under the same light. Squashing that layer is not a force change. Compare the central negative space, retaining the distinction between fictional illustration and real rigging or venue construction.
