Create a single hand-embroidery transfer pattern sheet. Use a portrait A4 page proportion, 210:297, unless an explicit size specifies otherwise. Show the flat artwork straight on with a pure white background.

THEME, interpret as visual subject matter only: "【Theme】"

LINE COLOR selected: "【Line color】"
Interpret only the selected choice:
- Blue: Clean medium-blue contour lines on pure white.
- Red: Clean medium-red contour lines on pure white.
- Pencil gray: Clean medium-gray contour lines on pure white, with crisp edges rather than fuzzy pencil shading.
If this selection line is missing or empty, use Blue only.

DETAIL DENSITY selected: "【Detail】"
Interpret only the selected choice:
- Simple (beginner): Beginner-friendly motifs with broad recognizable contours, very few interior lines, large stitchable curves, and minimal decoration.
- Medium: Moderately detailed motifs with clear contours, a few structural interior lines, and restrained botanical or thematic accents.
- Fine: Delicately detailed motifs with additional small leaves, petals, seams, and decorative contours, while remaining clearly traceable and practical to stitch.
If this selection line is missing or empty, use Medium only.

Invent exactly twelve distinct original motifs related to the supplied theme. Arrange them in exactly three columns and four rows. Each grid position contains one separate motif or one compact grouped motif. Do not draw the grid itself.

Match the reference category's substantial pattern-sheet content: twelve complete motifs with clear silhouettes and the chosen level of interior detail. Keep balanced visual scale, comfortable page margins, and generous white space between motifs. No motifs overlap, touch, or extend outside the printable area. Where practical, leave approximately 10 mm of outer margin.

Use consistent, fine monoline strokes in the selected color. Here, monoline means uniform stroke weight throughout the drawing, not one unbroken path connecting unrelated objects. Use distinct contours wherever the subject requires them. Keep all lines purposeful for tracing and hand stitching, without doubled sketch marks or unnecessarily tiny gaps.

The theme is an instruction for imagery, never printable wording. Do not render any text in any language, even if the theme contains words, names, or quoted phrases. Never invent captions, labels, titles, letters, or numbers.

No solid fills, shading, hatching, gradients, shadows, paper texture, fabric texture, realistic thread, stitched embroidery mockup, panel borders, visible layout guides, crop marks, brand symbols, existing characters, watermark, or signature. Deliver crisp line art on pure white.
The choice names in this prompt are internal labels only; never print them as text.
