Silk fabric by the yard
Buying silk fabric by the yard — understanding the different types, weights, and what to look for before purchasing.
Types of silk fabric
Charmeuse is woven in a satin weave — one side is lustrous and shiny, the other matte. It has a beautiful fluid drape and is the standard for luxurious blouses and bias-cut garments. Crepe de chine is matte, slightly textured, and very versatile — less slippery to cut and sew than charmeuse. Habotai, also called China silk, is lightweight, smooth, and even — widely used for lining and lightweight garments. Dupioni has a characteristic slubby texture from irregular yarns and a crisp, high-sheen surface — used for structured garments and occasion wear. Silk chiffon is sheer, very lightweight, and floaty. Silk organza is also sheer but crisp rather than floaty — used for structured overlay and couture techniques. Raw silk has a textured, irregular, matte surface and more rustic character than processed varieties.
Momme weight explained
Momme (abbreviated mm) is the standard weight measurement for silk fabric, similar to gsm for other textiles. The scale: 6-9mm is very lightweight and sheer, suited to scarves and delicate applications. 12-16mm is a medium weight — the range for most blouses, light dresses, and scarves. 19-25mm is heavier and more durable, the standard range for silk bedding, formal garments, and anything that will receive regular wear. 30mm and above is very heavy, used for structured garments and situations where durability is as important as feel. When in doubt about whether a silk is suitable for a project, momme weight is the most useful number to check.
Mulberry vs other silk
Mulberry silk is produced by Bombyx mori silkworms raised on a controlled diet of white mulberry leaves. The controlled environment and single food source produces very uniform, fine, bright-white filaments — the basis for the finest silk fabrics. It is the dominant type in the luxury market. Tussah silk (also called wild silk) comes from silkworms that feed on a varied diet of oak and other leaves in more open conditions. The resulting silk is coarser, less uniform, and naturally tan or brown in color. Tussah is considered more sustainable because the silkworms are not as intensively farmed, though both involve killing the silkworm pupae to unwind the cocoon. Peace or Ahimsa silk is produced using methods that allow the silkworm to emerge before the cocoon is processed.
What to look for when buying
Momme weight for the intended use is the first number to check. Fiber content should be 100% silk — blends with polyester are common and considerably less desirable in feel and performance. Country of origin matters: China and India are the dominant producers, with Thailand known for distinctive dupioni and heavier weaves. OEKO-TEX Standard 100 certification confirms the fabric is free of harmful chemicals in dyeing and finishing. For ethical sourcing, some suppliers specifically source from operations that use less intensive sericulture practices.
Sewing with silk
Use a fine needle — size 60/8 or 65/9 — to avoid leaving needle holes in the fabric. A shorter stitch length (1.8-2mm) works well. Pre-wash silk if the finished garment will be laundered — some silk shrinks and changes hand with washing. French seams are preferred for their neatness in sheer and lightweight silks. Silk is notoriously slippery to cut: tissue paper or pattern weights help hold fabric in place. Press with a low iron setting and always use a pressing cloth — direct high heat damages silk. Steam with care; too much moisture can water-spot some silks.
Common questions about buying silk by the yard
What does momme mean for silk?
Momme (mm) is the weight measurement used for silk, equivalent to grams per square meter (gsm) for other fabrics. A higher momme number means a heavier, denser, more durable silk. Low momme (6-9mm) is very sheer and lightweight. Mid-range (12-16mm) suits scarves, blouses, and lightweight garments. Higher momme (19-25mm) is used for bedding and more durable garments. 30mm and above is heavy enough for structured garments and upholstery. When comparing silk fabrics, momme weight is more informative than any other single specification.
What type of silk fabric is best for dresses?
Charmeuse and crepe de chine are the most commonly used silk fabrics for dresses. Charmeuse has a beautiful drape and sheen, suits bias-cut and fluid silhouettes. Crepe de chine is matte and slightly textured, with a versatile drape that works for both structured and fluid styles. Habotai is lightweight and smooth — good for lined dresses and underlining. Dupioni is crisp and textured with a distinctive slubby surface — better for structured styles. The right choice depends on the silhouette and how much drape vs structure the design requires.
How do you wash silk fabric?
Hand wash in cool water with a gentle silk-specific detergent, or use a machine's delicates cycle with cold water in a mesh laundry bag. Never wring or twist silk — squeeze gently and roll in a towel to remove excess water. Reshape while damp and dry flat or hang away from direct sunlight. Iron on the lowest setting with a pressing cloth while the fabric is still slightly damp, or steam very gently. Some silk fabrics are labeled dry clean only; follow the label.
What is the difference between silk charmeuse and silk satin?
Silk charmeuse is woven in a satin weave using silk threads, giving it a shiny surface on one side and a matte surface on the other. When people say "silk satin," they usually mean the same thing — charmeuse is a type of satin weave fabric. The confusion arises because "satin" also describes polyester fabric woven in the same structure. Silk charmeuse or silk satin is the real fiber; polyester satin mimics the surface appearance without the breathability, drape quality, or biodegradability of silk.
How much does silk fabric cost per yard?
Silk fabric prices vary widely by type, weight, and source. Habotai and basic charmeuse from Chinese producers typically runs $8-20 per yard. Mid-quality crepe de chine and charmeuse from reputable suppliers costs $18-35 per yard. Higher-end mulberry silk, specialty weaves, or silk from Indian or Thai producers can cost $30-80 per yard or more. Dupioni silk ranges widely from $15 to $50 depending on quality. OEKO-TEX certified silk at responsible retailers sits in the $25-45 range for most weights.
