Petersham ribbon is a ribbed, flexible corded ribbon with distinctive scalloped edges. Unlike conventional grosgrain ribbon with straight edges, Petersham is constructed to be shaped around curves, especially after steaming, which makes it particularly useful in millinery, hat making, sewing, tailoring, and any application where a ribbon needs to follow a curved edge without puckering.
Although Petersham and grosgrain look very similar at first glance — both share a ribbed texture and matte finish — they are not always interchangeable. This guide is written for sourcing professionals, milliners, garment manufacturers, and anyone who needs to specify the right ribbon for a curved application.
What Does Petersham Ribbon Look Like?
One of the most common problems in sourcing Petersham is that buyers often do not know whether the ribbon they are looking at is true Petersham or standard grosgrain. A close inspection reveals several visual characteristics.
| Feature | Petersham Ribbon |
|---|---|
| Surface | Ribbed (horizontal ridges) |
| Edge | Scalloped / picot |
| Hand feel | Firm but flexible |
| Shapeability | Can follow curves after steaming |
| Typical use | Millinery, hat making, sewing |
The scalloped edge is one of the most important functional characteristics of Petersham ribbon — it is not merely decorative. These edges are woven as part of the ribbon rather than cut or sealed afterwards, and this construction is what gives Petersham its ability to flex and conform to curved surfaces.
Petersham also has an identical front and back, which simplifies cutting and application during production.
How Is Petersham Ribbon Different from Grosgrain Ribbon?
This is the central question for most buyers searching for ribbon comparisons. The table below summarizes the key differences.
| Feature | Petersham Ribbon | Grosgrain Ribbon |
|---|---|---|
| Surface | Ribbed | Ribbed |
| Edge | Scalloped / picot | Straight / finished |
| Flexibility | More flexible around curves | Generally more rigid |
| Curved applications | Excellent | More limited |
| Steaming | Can be shaped with steam | Generally less suitable for shaping |
| Typical applications | Hat brims, millinery, waistbands | Bows, trims, hatbands, packaging, sewing |
| Main advantage | Follows curves without excessive puckering | Provides structure and a clean straight edge |
The easiest way to tell them apart is simply to look at the edge. Petersham has a scalloped or picot edge; grosgrain has a straight, sealed edge.
Grosgrain ribbon is woven with prominent transverse ribs and straight, tightly woven edges. The heavier weft yarns create a firm, structured ribbon that holds its shape well. Petersham ribbon also features a ribbed weave, but its defining feature is the scalloped edge along both sides.
A Note on Flexibility: Petersham vs. Grosgrain
Important: Many articles oversimplify the difference by stating that “grosgrain cannot curve.” This is not entirely accurate. Petersham is specifically constructed to accommodate curves, while standard grosgrain generally has a straighter, less shapeable edge. However, material, weave, finishing, fiber content, and construction all affect a ribbon’s flexibility. Some cotton grosgrain ribbons can be heat-shaped to a limited degree.
The more accurate and professional framing is this: Petersham is designed for curved applications. That distinction matters when specifying ribbon for production.
Why Can Petersham Ribbon Follow Curves?
Three factors work together to give Petersham its shapeability.
1. Scalloped edge. The picot or scalloped edge allows the ribbon to release tension when bent, preventing the puckering that occurs when a straight-edged ribbon is forced around a curve.
2. Woven construction. Petersham is woven with a structure that allows the ribbon to be molded after heat or moisture exposure. It has a crisp feel and can become stiffer when exposed to moisture or heat.
3. Steam shaping. In millinery practice, Petersham is held over steam from an iron or steamer for a few seconds, and while still warm and pliable, it is gently shaped to the required curve. Once cooled, the ribbon retains that shape and supports the curve of the piece it is applied to, maintaining a smooth and even appearance.
This steam-shaping capability is what separates Petersham from standard grosgrain in practical use, and it is the primary reason milliners specify Petersham for brim binding and curved hatbands.
What Is Petersham Ribbon Used For?
Hat Making & Millinery
This is the most important application for Petersham. It is used for hat brim binding, hat bands, crown finishing, sweatbands, and interior hat construction. Milliners rely on Petersham because hats are not flat structures — they contain circular curves, rounded edges, crown curves, and brim curves that require a ribbon capable of conforming to the shape of the hat without excessive puckering.
Sewing & Dressmaking
Petersham is used in waistbands, facings, curved seams, and garment finishing. Its ability to be pressed into a slightly curved shape makes it ideal for contoured waistband finishes on skirts and trousers. It is also used as a stabilizing ribbon in corsets and bodices.
Couture & Tailoring
In high-end garment construction, Petersham provides structure, clean finishing, curved edge support, and internal reinforcement. It is often used as a facing material by tailors and milliners alike.
Fashion Accessories
Petersham is also used for headwear, headbands, decorative trims, and structured accessories. It comes in a variety of widths, colors, and patterns including stripes and prints.
Petersham Ribbon for Hat Making
Because hats are built around curves, the ribbon used on a hat must follow those curves without wrinkling or gathering. Petersham is designed for exactly this purpose.
Brim Binding. Petersham can be steamed and shaped to follow the curve of a hat brim. It is available in fold-over constructions with a thinned center line for ease of folding, making it ideal for finishing brims and hat trims.
Crown Band. Petersham is used to wrap around hat crowns and create decorative or structural bands. Wider widths are commonly used for this purpose.
Sweatband / Interior Finishing. Petersham is also used for interior hat construction and finishing, where its ability to conform to the interior curve of the hat is essential.
It is worth noting that not all hat bands should be Petersham. Many traditional hatbands use standard grosgrain, which provides a crisp, structured appearance. The choice depends on whether the band needs to follow a curve or maintain a straight, structured look.
Petersham Ribbon vs. Grosgrain Ribbon: Which One Should You Choose?
The answer depends entirely on the application. Neither ribbon is universally “better” — they are designed for different purposes.
Choose Petersham when:
- You need to follow a curve
- You are making hats or millinery
- You need steam shaping
- You are binding a curved edge
- You need flexible edge finishing
- You are constructing contoured waistbands
Choose Grosgrain when:
- You need a straight edge
- You want a more structured trim
- You are making bows or flat decorative trims
- You need a clean, tailored finish on straight edges
- You are reinforcing straight seams or packaging
How to Identify True Petersham Ribbon
Petersham and grosgrain are often confused in the market, and some suppliers use the terms interchangeably. Before purchasing, use this checklist:
- Edge. Is it scalloped or picot? If the edge is straight and sealed, it is likely grosgrain.
- Shapeability. Can the ribbon be steamed and shaped into a curve? If it resists shaping, it is not Petersham.
- Material. What fiber is used? Natural fibers such as cotton, rayon, and viscose are traditionally used in Petersham.
- Construction. How is the ribbon woven? Petersham is typically woven on shuttle looms with a scalloped edge structure.
- Intended application. Is it marketed for millinery or general decorative use? Millinery-grade Petersham is made specifically for hat making.
What Materials Is Petersham Ribbon Made From?
Petersham can be produced from different fibers depending on the required hand feel, flexibility, durability, colorfastness, and end use. Common materials include:
- Cotton — traditional, crisp, natural hand feel
- Rayon / Viscose — soft, drapable, excellent shapeability
- Cotton / Viscose blends — balanced properties for millinery use
- Polyester — durable, colorfast, cost-effective options
- Silk — premium option for high-end applications
- Metallic / Lurex blends — decorative variants with sparkle
For example, French millinery Petersham is commonly available in 50% cotton / 50% viscose, while other suppliers offer 100% rayon or 100% cotton versions. Polyester Petersham is also produced for buyers who prioritize durability and cost efficiency over natural fiber content.
For millinery applications, natural fibers are generally preferred because they respond better to steam shaping than synthetic fibers.
