Damask & Medallion Woven Jacquard for Curtains: GSM & Repeat Placement Guide

Published by Jacquard Works | July 2026

Introduction

Selecting woven jacquard for curtains and drapery involves different criteria than upholstery: the fabric must hang cleanly, transmit or block light predictably, and position its repeat at the window without costly fabric waste. This guide covers GSM selection, construction differences between floral and medallion woven jacquard, and a practical repeat-placement checklist for buyers specifying curtain fabric at volume.

1. Why Woven Jacquard Performs Differently at the Window

Upholstery jacquard is engineered for abrasion resistance and dimensional stability under compression. Curtain jacquard prioritises drape coefficient, light filtration, and repeat registration across multiple panel widths. A fabric that performs well on a sofa seat may be too stiff to form clean folds at a window, or too light to block ambient light in a hospitality bedroom.

The key variables are GSM, yarn type, and weave density. Polyester-dominant constructions at 280–320gsm produce a fluid drape with moderate light filtration — suitable for sheer-adjacent decorative drapery. Polyester-cotton blends at 340–380gsm add body and opacity, making them appropriate for blackout-lined curtain panels in contract and hospitality environments. Warp-faced jacquard constructions, where the pattern yarn runs lengthwise, resist sagging over long drop lengths better than weft-faced alternatives.

• Drape coefficient: Lower GSM = more fluid fold; higher GSM = structured pleat retention
• Light filtration: Polyester-cotton blends at 350gsm+ reduce light transmission by 60–75% unlined
• Repeat registration: Large-scale repeats (25cm+) require pattern-matching allowance of 1.5× repeat per panel join
• Shrinkage: 100% polyester constructions offer <1% dimensional change; cotton-blend constructions require pre-shrink finishing for made-to-measure orders

Our Royal Purple Floral Woven Jacquard at 300gsm and Navy Peony Floral Woven Jacquard at 360gsm illustrate the two ends of this GSM range — the former suited to decorative drapery, the latter to lined contract panels.

2. Floral vs Medallion Woven Jacquard: Construction & Placement Comparison

Floral Woven Jacquard

Floral woven jacquard uses a multi-shuttle or dobby-assisted loom to interlace pattern yarns in organic, non-repeating-axis motifs. The result is a fabric with directional visual flow — the eye follows the bloom arrangement rather than a geometric grid. For curtains, this means the repeat can be centred on the panel width without strict symmetry requirements, reducing cut waste on non-standard window widths.

• Pattern axis: Organic / non-geometric — tolerates off-centre placement
• Repeat scale: Typically 20–40cm vertical repeat; large-scale peony/hydrangea motifs run 35–45cm
• Yarn structure: Multi-colour weft insertion; polyester-cotton blends add surface depth
• Best application: Decorative drapery, hospitality guest rooms, residential living rooms

Our Navy Peony Floral Woven Jacquard at 360gsm features a large-scale peony and hydrangea bouquet in a polyester-cotton blend, with a 150cm width that accommodates standard double-pleat panel cuts without a join seam.

Medallion Woven Jacquard

Medallion and damask-style woven jacquard organises its motif around a central geometric axis — typically a radial or bilateral repeat. This construction demands precise repeat registration: the medallion centre must align horizontally across all panels in a multi-window installation. Misalignment by even half a repeat is visually apparent at scale. Medallion constructions are typically woven at higher pick counts (120–160 picks/cm²), producing a denser, more structured hand that holds a pinch pleat or eyelet heading without interlining.

• Pattern axis: Bilateral / radial — requires strict horizontal registration across panels
• Repeat scale: Typically 30–60cm; large medallions require 1.5–2× repeat allowance per panel
• Yarn structure: Often incorporates chenille or textured weft for relief depth on the medallion body
• Best application: Formal living rooms, hotel lobbies, banquet halls, contract drapery

Our Ivory Qilin Medallion Woven Jacquard at 350gsm uses a figural medallion repeat with chenille-yarn weft insertion, producing a raised surface texture that reads as dimensional at window scale.

3. Buyer QC Checklist

GSM & Construction Verification

• Confirm GSM via lab report or supplier test certificate — not product description alone
• Verify pick count (picks/cm²) for medallion constructions; request loom card or weave spec sheet
• Check fibre composition: polyester-cotton blends require pre-shrink finishing declaration for made-to-measure orders

Repeat Placement & Cut Planning

• Request a physical repeat card or digital repeat diagram before bulk order
• For medallion constructions: confirm repeat height and width; calculate cut allowance at 1.5–2× repeat per panel
• For floral constructions: confirm directional orientation (one-way vs two-way) to avoid panel reversal in multi-window installations
• Specify drop length + heading allowance + hem allowance in your purchase order — not finished panel length only

Colour & Batch Consistency

• Request shade band (A/B/C tolerance) for all colourways in the order
• For multi-roll orders: specify maximum dye lot variation tolerance (ΔE ≤ 1.5 recommended for contract drapery)
• Confirm selvedge-to-selvedge colour consistency — jacquard looms can produce edge shading on wide-width constructions
• Request pre-production strike-off for custom colourways before bulk weaving begins

Conclusion

For curtain and drapery applications, the choice between floral and medallion woven jacquard comes down to installation context and repeat-management budget: floral constructions offer more placement flexibility at lower cut waste, while medallion constructions deliver formal visual impact at the cost of stricter registration discipline. Specify GSM, repeat dimensions, and fibre composition in your purchase order — not pattern name alone.
