Interfacing adds support, stability and body to fabric, whether you're making clothes, bags, quilts or accessories. But should you choose woven or non-woven?
Neither is automatically better. The right choice depends on your fabric, your pattern and the finish you want. Construction is only part of the decision: weight, application method and care requirements matter too.
This guide explains the differences, introduces practical examples from our range and helps you choose a suitable product without assuming that every interfacing behaves the same way.
What is interfacing?
Interfacing is a supporting material attached to fabric or enclosed between fabric layers. It can reinforce collars, cuffs, button plackets, waistbands, facings and pockets, or add body to bags, accessories and craft projects.
Two separate distinctions are important:
- Woven or non-woven: how the supporting material is constructed.
- Fusible or sew-in: how it is attached to your fabric.
Foam-based interlinings and other specialist stabilisers also have their place, but should not be treated as interchangeable with ordinary woven or non-woven interfacing.
What is woven interfacing?
Woven interfacing has threads woven together into a fabric-like material. It has a grain direction, so position and cut it according to the product guidance and your pattern.
A suitable woven interfacing can support fabric while retaining some of its natural movement. It is commonly used for collars, cuffs, facings, plackets, waistbands, pockets and yokes, as well as selected bag-making and craft applications.
Advantages of woven interfacing
- A fabric-like construction that can work well alongside woven dress fabrics.
- A choice of weights and finishes for different levels of support.
- Useful reinforcement for garment details without necessarily creating a rigid result.
Limitations to consider
- Grain direction matters when cutting and positioning.
- It can still change drape, feel and appearance, particularly if too heavy for the fabric.
- Ordinary woven cotton interfacing may not provide enough structure for a firm handbag.
- A woven interfacing can restrict stretch, even when the product is suitable for some knit fabrics.

What is non-woven interfacing?
Non-woven interfacing is made from fibres bonded together rather than woven into threads with a conventional warp and weft grain. Some products still have a preferred direction or different stretch characteristics, so follow their instructions rather than assuming they can always be cut any way.
Non-woven does not mean stiff. Products range from soft, lightweight garment interfacings to firm specialist stabilisers.
Advantages of non-woven interfacing
- A broad choice of weights and finishes for garments, accessories and crafts.
- No conventional woven grain, although product-specific direction guidance may apply.
- Options for subtle reinforcement as well as substantial structure.
Limitations to consider
- The wrong weight can overpower a lightweight fabric.
- Some products noticeably change drape or surface appearance.
- Specialist stabilisers may need different preparation and handling from ordinary dressmaking interfacing.
Woven vs non-woven interfacing: a quick comparison
| Feature | Woven | Non-woven |
|---|---|---|
| Construction | Threads woven together | Fibres bonded together |
| Grain | Has a woven grain direction | No conventional woven grain; check directional guidance |
| Feel and drape | Fabric-like, but affected by weight, finish and adhesive | Varies from soft and flexible to firm |
| Dressmaking | Suitable products for garment details | Suitable products for garment details |
| Bag making | Can reinforce outer fabric and softer bags | Options from light support to firm stabilisation |
| Attachment | Fusible and sew-in types exist | Fusible and sew-in types exist |
Choose by the individual specification and your test result, not construction alone. A soft non-woven and an ultra-firm stabiliser serve very different purposes, just as two woven products can give different finishes.
Which interfacing should you choose for your project?
Shirts, blouses, collars and cuffs
Start with the garment pattern's recommendation. Both woven and non-woven products can work, provided the support, drape and care requirements suit your fabric.
Woven options include Vlieseline G700, Hemline HN100, Vlieseline B700 and Pellon SF101 Shape-Flex.
A non-woven option such as Vlieseline H250 may also suit selected garment details, depending on the pattern, fabric and desired finish. Test first rather than assuming woven is always preferable for clothing.
Bags, purses and accessories
A soft pouch may need only fabric reinforcement, while a structured handbag may require a dedicated stabiliser or more than one supporting layer as directed by its pattern.
SF101 is used for bags and pouches, particularly in patterns that name it. For a firmer or padded finish, consider the specialist examples below. A stiff stabiliser and a padded foam do different jobs, so they are not automatic substitutes.
Waistbands and belts
The level of support depends on the garment and fabric. A suitable woven product may retain a fabric-like finish; a stable non-woven or specialist waistband product may better suit a firmer result. Follow the pattern and test for comfort as well as support.
Quilting and embroidery
Distinguish permanent fabric reinforcement from an embroidery stabiliser intended to be removed after stitching. Quilting may also call for fleece or batting rather than ordinary interfacing. Choose for the technique and intended finish.
SF101's stated uses include backing for needlework and punch embroidery, but that does not make it the right stabiliser for every embroidery method.
Delicate, sheer or heat-sensitive fabrics
Check whether heat, pressure or adhesive could mark the fabric or alter its drape. A suitably lightweight woven or non-woven product may work; an appropriate sew-in may be preferable where fusing is unsuitable. Test on an offcut before working on the garment.
Fusible vs sew-in interfacing
Fusible interfacing
A fusible product has adhesive that bonds to fabric using heat. It can be convenient, but needs the correct temperature, pressure, moisture and pressing time. Not every product uses a damp cloth or steam.
Sew-in interfacing
A sew-in product is secured by stitching rather than adhesive. It can be useful where you do not want to bond the layers or where fusing would be unsuitable for the fabric. Follow your pattern for securing it and managing seam allowances.
Both woven and non-woven interfacings can be fusible or sew-in. Knowing just one of these characteristics is not enough to identify a suitable product.
Woven cotton interfacing examples from our range
| Product | Weight | Width | Useful starting point for |
|---|---|---|---|
| Vlieseline G700 | 90gsm | 90cm | Shirt and blouse collars and cuffs |
| Vlieseline B700 | 90gsm | 90cm | Small garment sections, with biodegradable adhesive |
| Hemline HN100 | 90gsm | 90cm | Collars, cuffs and garment details |
| Pellon SF101 | GSM not specified in our listing | 20″ / 50.8cm | Garment details, accessories and needlework |
| TYSG Cotton Woven | Approx. 80gsm including adhesive | 112cm | Cotton fabric reinforcement and general sewing |
These products have cotton bases with fusible adhesive. Similar base materials and weights do not guarantee identical feel, bonding or care requirements.
G700, B700 and HN100
All three are 100% cotton woven products, 90gsm and 90cm wide. G700 is described by Vlieseline as heavyweight while HN100 is described by Hemline as standard medium-weight; both are recommended for light- to medium-weight fabrics. Weight labels alone are not a reliable basis for substitution.
B700's adhesive is its distinguishing feature, and its care guidance differs: it is washable up to 30°C, compared with up to 60°C for G700 and HN100. A biodegradable adhesive does not establish the environmental impact or biodegradability of your finished garment.
SF101 cut lengths and pre-packs
Choose SF101 cut from the roll for a 10cm × 10cm sample or half-metre increments. Multiple half-metre quantities are supplied as one continuous length.
The separate SF101 1-yard pre-pack measures 20″ × 1 yard, approximately 50.8cm × 91.4cm. Each quantity is a separate pack, not a continuous piece when ordering multiples. Check yards versus metres when following a pattern.
Pellon recommends pre-shrinking SF101 by soaking in warm water for about 10 minutes, gently squeezing out excess water and line drying. Do not machine wash or tumble dry the interfacing alone to pre-shrink it, as this may loosen the adhesive. Follow its specific application instructions.
Our wider cotton woven alternative
Our own-range woven fusible interfacing comes in white and black. It has a 100% cotton base, polyamide adhesive, an overall weight of approximately 80gsm and a 112cm width. It is washable up to 40°C.
The additional width may suit your cutting layout, but compare usable width, current price and the amount needed rather than price per metre alone. It is an alternative, not an identical replacement for G700 or SF101.
Non-woven interfacing and firm stabiliser examples
Vlieseline H250
H250 is a stable fusible non-woven interfacing, 62gsm and 90cm wide, made from 60% polyester and 40% cellulose. It provides a crisp finish for suitable garment and craft applications. Follow its dry-iron application guidance rather than assuming it uses the same damp-cloth method as G700.
White non-woven interfacing in light, medium and heavy weights
Our white fusible non-woven range is 75cm wide and offers light, medium and heavy options. Its polyester base has an LDPE adhesive coating. These weight labels apply within this range, not across every manufacturer's products.
Check its own care and application instructions: the listing specifies a 30°C delicate/quick wash and no dry cleaning.
Decovil I Light and Decovil I Heavy
Decovil I Light and Decovil I Heavy are specialist fusible products with a firm, leather-like handle for suitable bags, belts and structured accessories. Light and Heavy offer different levels of body, not the padded feel of foam.
Pellon Peltex: check the version
Pellon 71F Peltex I is an ultra-firm non-woven stabiliser with adhesive on one side. Pellon 72F Peltex II is fusible on both sides. Both are 20″ (50.8cm) wide, but the different adhesive arrangements matter when planning fabric layers.
Do not choose solely by the Peltex name: use the version and application method required by your pattern.
Where does foam interfacing fit?
Foam-based interlinings are a separate practical category from ordinary woven and bonded-fibre interfacings.
Vlieseline Style-Vil Fix is a fusible foam product for padding and stabilisation in suitable bags, pouches and cases. Its padded feel is different from a firm sheet stabiliser such as Peltex or the leather-like handle of Decovil.
Choose the effect your pattern needs: support, firmness and padding are not the same thing. Follow the product's own application and seam-handling guidance.
How to choose: five questions before buying
- What does the pattern recommend? Begin with the specified type and product, especially where construction depends on a particular finish.
- How much support is needed? A shirt collar and a structured handbag need different results.
- Must the fabric retain drape or stretch? Check the fused test piece. SF101 is suitable for some light- to medium-weight knits, but a woven layer can restrict stretch where it is needed.
- Can the fabric tolerate the application? Check heat, pressure, moisture and any preparation such as pre-shrinking.
- How will the finished item be cared for? Match the materials' care requirements and check width and ordering units before purchasing.
Always test your interfacing first
Apply a small piece to an offcut of the actual project fabric, following the chosen product's instructions. Let it cool for the required time before judging the result.
Check the bond, support, drape, stretch, colour, surface appearance and any puckering. Where practical, test laundering in the way you intend to care for the finished item.
Lift and reposition the iron rather than sliding it, and use only the temperature, moisture, pressure and timing recommended for that product.
Frequently asked questions
Is woven interfacing better than non-woven?
No. Either can work well when the individual product suits the fabric and project. Neither construction guarantees a particular finish.
Can I use non-woven interfacing for clothes?
Yes. Many non-woven products are intended for dressmaking. Match the weight, feel and application method to your fabric rather than assuming clothing always needs woven interfacing.
Can I use woven interfacing for bags?
Yes, for suitable fabric reinforcement and softer structures. A firm bag may need a dedicated stabiliser or supporting layers as specified by its pattern.
Does non-woven interfacing have a grain?
It has no conventional woven warp and weft grain, but some products have directional properties. Follow the manufacturer's cutting guidance.
Can I wash fabric after applying fusible interfacing?
Many products are washable, but temperatures, drying and dry-cleaning guidance vary. Follow the care requirements of the finished item's least washable component, including the outer fabric, lining, interfacing and trims.
What is the best interfacing for beginners?
Start with the type recommended by your pattern and fabric choice, then test a sample. There isn't one beginner product that is suitable for every project.
