Fabrics Explained
A Simple Guide to Buying Fabric Online
Buying fabric online can feel confusing – especially if you’re new to sewing or you’re used to feeling the fabric in a shop before you decide.
This page is here to keep things simple and honest. We’ll explain:
- What fabric weight (gsm) actually means
- What terms like needlecord, dobby, jacquard, denim, fleece mean in plain English
- How corduroy wales work (those little ridges!)
- What you might want to make with each type of fabric
Every fabric we sell on Rich Fabrics links back to this page, and most of our live-sale fabrics also have a video clip so you can see them moving in real life.

How We Sell Fabric
3 metre pieces (with continuous length if you order more)
Most of our fabrics are sold in 3 metre pieces. That’s enough for:
- A dress
- Trousers or dungarees
- Skirts + a top
- Several children’s garments
If you order more than one 3 metre piece of the same fabric, we’ll send it as one continuous length where possible, cut straight from the roll (unless the listing clearly says they are pre-cut).
UK-only, tracked postage
We currently post within the UK only, usually via Royal Mail Tracked 24 or 48. Postage is calculated by weight, which is why we show gsm and give each 3 metre piece a clear weight on the website.

Fabric Weight (GSM) Explained
What is gsm?
We show fabric weight in gsm – grams per square metre. You don’t need to do any maths. Just think of gsm as:
How thick or thin the fabric feels in your hand.
On each product page, we’ll tell you:
- The gsm
- Which band it sits in (light, medium, heavy, etc.)
- What it feels similar to (e.g. “like a light denim” or “like a standard shirt fabric”)
- Some project ideas it’s suitable for
We also try to include a live-sale video clip on many fabric listings so you can see the drape and thickness in real life before you decide.
As a rough guide:
-
Very light (70–110gsm)
Very floaty, delicate, airy.
Sheer tops, overlays, scarves, layering.
-
Light (110–150gsm)
Light and soft, like a standard cotton shirt.
Shirts, blouses, lighter dresses, kids’ clothes
-
Medium (150–230gsm)
A good “all-round” dressmaking weight.
Dresses, skirts, shirts, pyjamas, loose trousers
-
Medium-Heavy (230–280gsm)
Sturdier and more structured, holds its shape.
Good for: dungarees, pinafores, lighter denim projects, bags, jackets.
-
Heavy (280gsm and up)
Thick and robust – a true “workwear” feel.
Good for: jeans, coats, strong bags, upholstery.
Corduroy & Wales Per Inch (Those Little Ridges!)
What are “wales”?
Corduroy has little ridges running down the length of the fabric. Those ridges are called wales.
When we say “14 wales per inch” or “24 wales per inch”, we’re telling you how big or small those ribs are:
- Fewer wales per inch → bigger, chunkier ribs (often called jumbo cord)
- More wales per inch → finer, smaller ribs, sometimes called needlecord or feather cord
Rough guide:
- 4–8 wales per inch – big chunky cord, very textured.
- 8–12 wales per inch – standard dressmaking cord.
- 14–18 wales per inch – fine needlecord; softer, more “suited” look.
- 20+ wales per inch – very fine, often called feather cord; texture is subtle.
In our listings, we always give the wale count, so you know whether you’re buying:
- A chunky, cosy cord for jackets and dungarees
- Or a fine needlecord that’s softer and more drapey for dresses and shirts
Look for the line that says “Approx. 14 wales per inch” or similar in our cord listings for a quick feel for how fine or chunky it is.

Cotton Fabrics
Cotton is one of the most popular and versatile fabrics used in sewing. It’s breathable, comfortable to wear and relatively easy to sew, which is why many beginners start with cotton fabrics.
Cotton fabrics come in many different textures and weights depending on how they are woven.
Common cotton fabrics we sell
• Cotton poplin
• Cotton dobby
• Cotton honeycomb
• Cotton drill
• Calico
Typical weight range
Light to medium (around 110–250gsm depending on the weave)
What cotton fabrics are good for
• Dresses
• Shirts and blouses
• Children's clothing
• Pyjamas
• Skirts
• Crafts and quilting
• Lightweight curtains
Helpful things to know before buying
• Cotton is breathable and comfortable to wear.
• Most cotton fabrics are easy to cut and sew.
• Some cotton fabrics may shrink slightly when washed, so pre-washing is often recommended.
• Lighter cottons drape well, heavier cottons hold more structure.
Beginner tip
Cotton fabrics are usually one of the easiest fabrics to sew, which makes them ideal if you're learning.
Polycotton
Polycotton is a blend of polyester and cotton fibres. It combines the softness and breathability of cotton with the durability and wrinkle-resistance of polyester.
Because of this blend, polycotton fabrics are often very practical and easy to care for.
Typical weight range
Lightweight (around 90–130gsm)
What polycotton is good for
• Crafts and quilting
• Children's clothing
• Cushion covers
• Lightweight dresses and shirts
• Bags and accessories
Helpful things to know before buying
• Polycotton usually holds its shape well.
• It tends to crease less than pure cotton.
• It’s often slightly firmer than very soft cotton fabrics.
• It’s generally very easy to sew.
Beginner tip
Polycotton is popular for beginners because it’s stable and predictable when sewing.
Viscose
Viscose is a lightweight dress fabric known for its soft feel and beautiful drape. It’s made from natural plant cellulose (usually wood pulp) that has been processed into fibres and spun into fabric.
Because of this, viscose is often described as feeling like a blend between cotton and silk — soft, breathable and flowing.
Viscose fabrics are very popular in dressmaking because they move beautifully and feel comfortable to wear.
Typical Weight Range
Most viscose dress fabrics fall into the lightweight category (around 110–150gsm), although heavier versions do exist.
Lightweight viscose fabrics are commonly used for garments that are designed to drape and move.
What Viscose Fabrics Are Good For
• Dresses
• Blouses
• Skirts
• Lightweight trousers
• Summer clothing
• Floaty tops
Because viscose has a natural drape, it’s ideal for garments where you want movement rather than stiffness.
What Viscose Feels Like
Viscose fabrics are typically:
• Soft and smooth
• Lightweight and breathable
• Fluid with a flowing drape
• Comfortable against the skin
Many people describe viscose as having a feel similar to soft cotton but with more movement.
Helpful Things To Know Before Buying
Viscose behaves differently from many cotton fabrics, so there are a few things worth knowing:
• Viscose drapes beautifully but can feel slightly slippery when cutting and sewing.
• Lightweight viscose fabrics can move around more on the sewing table than stiffer fabrics.
• Because of the drape, viscose is usually better for flowing garments than structured garments.
• Viscose can shrink slightly if washed hot, so gentle washing is usually recommended.
Beginner Tip
Viscose isn’t difficult to sew, but because it’s soft and fluid it can take a little more care when cutting and handling compared to very stable fabrics like cotton.
Using sharp scissors and taking your time when cutting usually makes the process much easier.
How Viscose Compares To Cotton
Viscose and cotton are both popular fabrics for dressmaking, but they behave quite differently when sewn and worn.
Cotton fabrics tend to be more structured and stable. They hold their shape well and are usually easier to cut and sew, which is why they’re often recommended for beginners.
Viscose fabrics, on the other hand, are known for their soft drape and fluid movement. They flow and move with the body rather than holding a rigid shape.
Because of this difference, the same garment pattern can look very different depending on whether it’s made from cotton or viscose.
Cotton tends to be:
• More structured
• Easier to cut and sew
• Slightly firmer in handle
• Good for garments that need shape or structure
Viscose tends to be:
• Softer and more fluid
• More drapey and flowing
• Slightly more slippery to handle when sewing
• Ideal for garments designed to move
Both fabrics are breathable and comfortable to wear, but viscose is usually chosen when a softer, more elegant drape is desired.
When To Choose Viscose Instead Of Cotton
Viscose is often the better choice when you want garments that move and drape naturally.
It works particularly well for:
• Floaty dresses
• Soft blouses
• Wrap dresses
• Flowing skirts
• Lightweight summer clothing
If a pattern calls for a fabric with drape, viscose is often a very good option.
Cotton fabrics may be a better choice when a garment needs more structure, such as shirts, fitted garments, or projects where a crisp shape is preferred.
Sewing Tips For Viscose Fabrics
Because viscose is soft and fluid, it behaves a little differently from more structured fabrics like cotton.
A few simple tips can make sewing with viscose much easier:
• Use sharp fabric scissors or a rotary cutter for clean cutting.
• Take your time when laying the fabric out, as lightweight viscose can shift slightly.
• Use fine pins or clips to avoid marking delicate fabrics.
• A universal or microtex needle usually works well.
Once sewn, viscose garments are often extremely comfortable to wear, which is one of the reasons they remain so popular in dressmaking.
A Quick Note About Fabric Drape
One of the most important things to consider when choosing fabric is drape.
Drape refers to how a fabric hangs and moves.
• Structured fabrics hold their shape.
• Drapey fabrics flow and move.
Viscose fabrics are known for having excellent drape, which is why they’re commonly used for dresses, blouses and other garments designed to move naturally with the body.
Linen & Linen Blends
Linen fabrics are made from flax fibres and are known for their natural texture and breathability.
Some fabrics have a linen look but are actually cotton or polyester blends designed to mimic linen’s appearance.

What linen fabrics are good for
• Dresses
