Autumn sewing is a weight problem, not a colour problem. The autumn fabrics UK sewists actually reach for come down to five: corduroy, brushed cotton, wool coating, polar fleece and tartan. The number that separates them is GSM, not the fibre name on the label. Below are the weights, the makes, the metreage and the cost of each.
GSM means grams per square metre, and it is the single most useful figure on a fabric listing. A summer cotton lawn is around 80–110gsm. A brushed cotton is 130–200gsm. Corduroy starts around 190gsm for needlecord and climbs to 450gsm for jumbo cord. Wool coating runs 350–600gsm, and heavy melton can pass 700gsm. Those are typical ranges rather than universal ones; two fabrics with the same name can be 100gsm apart depending on the supplier, so check the GSM stated on the listing before you commit.
Once you have the weight, everything else follows. Weight tells you whether a fabric will hang or stand away from the body, whether your machine will cope, whether it needs lining, and roughly how warm it will be. If you want the longer version of that argument, read how fabric weight affects drape and fit. For the shopping side of it, the warm and cosy collection is where the heavier autumn cloth lives.
One honest caveat before the numbers. Warmth is not GSM alone. A 250gsm polar fleece feels warmer against the skin than a 250gsm woven cotton, because fleece holds a huge volume of still air in its lofted surface and air is the actual insulator. Weight tells you how much material is there; construction tells you how much air that material can trap. Both matter, and the table below accounts for the second one.
The five autumn workhorses
Everything in this section is available at a couple of pounds a metre or less, which changes what you can reasonably attempt. At £12/m, a coat is a serious financial decision. At £2/m, a coat is a Saturday.
| Fabric | Typical GSM | Warmth | Drape | Difficulty | Typical width |
|---|---|---|---|---|---|
| Brushed cotton / winceyette | 130–200 | Mild | Soft, fluid | Easiest | 112–150cm |
| Needlecord | 190–260 | Mild to moderate | Soft with body | Easy, but napped | 140–150cm |
| Polar fleece | 180–300 | High for its weight | Bulky, no drape | Easy, no hemming | 150–160cm |
| Tartan (polyviscose) | 200–260 | Moderate | Crisp, holds pleats | Easy to sew, fiddly to cut | 145–150cm |
| Standard / jumbo cord | 260–450 | Moderate to high | Stiff, structural | Moderate | 140–150cm |
| Wool coating | 350–600 | Highest | Heavy, sculptural | Hardest | 145–150cm |
Brushed cotton
A plain woven cotton with the surface raised on one or both sides, so it feels soft and slightly fuzzy. Sold as brushed cotton, flannel or winceyette depending on the weight and the seller. It sews exactly like quilting cotton — universal 80/12 needle, 2.5mm stitch, no special handling — which makes it the sensible starting point if you have never sewn anything heavier than a cotton poplin. It creases, it shrinks on the first wash (prewash it), and it pills a little with age. For pyjamas, shirts, nightdresses, baby blankets and toddler dresses it is unbeatable at this price.
Corduroy
A cut-pile cotton with lengthwise ridges. It is warmer than a plain cotton of the same weight because the pile holds air, and it is far more hard-wearing than its price suggests. The trade-off is the nap: every piece must be cut facing the same direction or the colour will read differently panel to panel. That costs you fabric, and it is the single most common corduroy mistake. Full detail on the wale sizes and the nap rule is in is corduroy warm. Browse the corduroy range for what is in stock.
Wool coating
The warmest thing on this list per centimetre of thickness, because wool fibre crimps and traps air right through the cloth rather than only at the surface. It also holds a pressed shape better than any synthetic, which is why tailored jackets are made from it. It is the hardest of the five to sew: it needs a 90/14 needle, a longer 3–3.5mm stitch, a good steam press and, for anything tailored, interfacing at the front edges and collar. Do not skip pressing seams open as you go; wool that has not been pressed at each stage will never look right afterwards. See the wool fabrics range.
Polar fleece
Knitted polyester, brushed on both faces into a deep pile. Nothing else on this list gives you as much warmth for as little weight or money. It does not fray, so hems and seam finishes are optional, which cuts a beginner project down to almost nothing. Its weaknesses are real, though: it has no drape at all, so it makes shapeless clothes unless the pattern is designed for it; it pills unless you buy anti-pill; and it melts rather than chars, so it is a poor choice near open flame. Sew it with a 75/11 ballpoint or stretch needle and a narrow zigzag or walking foot.
Tartan
Tartan is a pattern rather than a fibre, and it turns up in polyviscose (200–260gsm, crisp, pleats beautifully, cheapest), brushed cotton (150–200gsm, soft, shirt weight) and wool (300–450gsm, heavy, the real thing). All of them share one cost that no other fabric here has: the pattern repeat. If the checks have to line up across a seam, you pay for that in extra metres. The maths is in what to make with tartan fabric, and the range is in tartan fabrics.
Eight autumn makes, with metreage and cost
Every figure below assumes 150cm-wide fabric unless stated, standard UK sizing, and a one-way nap layout where the fabric has one (corduroy, fleece and velvet all do). The two price columns are worked examples at indicative rates, not live prices — check the listing for the real figure on the day.
| Make | Fabric | Metreage | At £1/m | At £3/m | Note |
|---|---|---|---|---|---|
| Pinafore dress, sizes 8–14 | Needlecord | 1.8m | £1.80 | £5.40 | 2.1m for sizes 16–24 |
| Cord trousers | Standard cord | 1.7m | £1.70 | £5.10 | 2.0m for sizes 16–24 |
| Long-sleeve flannel shirt | Brushed cotton, 112cm wide | 2.2m | £2.20 | £6.60 | 1.7m if the fabric is 150cm |
| Sofa throw, 150 x 200cm | Polar fleece | 2.0m | £2.00 | £6.00 | No hemming needed |
| Four fringed scarves | Tartan | 1.8m | £1.80 (45p each) | £5.40 (£1.35 each) | Cut lengthwise, 4 x 35cm strips |
| Lined A-line skirt | Tartan outer + lining | 1.5m outer + 1.0m lining | £2.50 | £7.50 | Outer includes 0.3m for matching |
| Adult hoodie | Polar fleece | 2.0m | £2.00 | £6.00 | Add 0.2m for a lined hood |
| Four 45cm cushion covers | Tartan or cord | 1.5m | £1.50 | £4.50 | 1.9m if you centre the check |
Take the pinafore as the worked example, because it is the one people ask about most. A standard pinafore has four major pieces: bodice front, bodice back, skirt front, skirt back. On 150cm-wide cord, the two bodice pieces sit side by side across the width, and the two skirt pieces sit side by side below them. That is roughly 55cm for the bodice run and 75cm for the skirt run, plus facings and a 10cm safety margin: 1.8m. Because corduroy is napped, you cannot rotate one piece to nest it into a gap, which is why the figure does not drop below 1.8m however clever your layout is. At an indicative £1/m that is £1.80 of fabric. A comparable ready-made cord pinafore on the high street was around £30–£40 at the time of writing.
The scarves are the clearest illustration of what cheap fabric by the metre changes. A scarf wants to be around 180cm long, so cut it along the length of the fabric rather than across the width. Buy 1.8m of 150cm-wide tartan, cut four strips 35cm deep running the full 1.8m, fringe the short ends by pulling threads, and you have four scarves for £1.80 at an indicative £1/m. Christmas presents, done in an afternoon, 45p each.
What to sew first if you have never sewn a warm fabric
Heavier cloth is not harder to sew, but it is less forgiving of a bad plan. Bulk collects at seam intersections, pins leave marks in pile, and a wool that has been pressed badly cannot be un-pressed. Work up in this order.
- Fleece throw, 2.0m, £2.00 at £1/m. Cut a 150 x 200cm rectangle. Leave the edges raw or cut a 2cm fringe into the short ends. There is no sewing at all in the simplest version. It teaches you how a heavy fabric behaves under the rotary cutter and nothing else.
- Cushion covers, 1.5m for four, £1.50 at £1/m. Straight seams, an envelope back, no zip. You learn how a napped or checked fabric looks when two panels meet, which is the lesson that matters later.
- Brushed cotton pyjama bottoms, 1.8m, £1.80 at £1/m. An elasticated waist, two side seams, two inseams, a crotch curve. Warm fabric, but it handles like the quilting cotton you already know.
- Needlecord pinafore, 1.8m, £1.80 at £1/m. Your first napped garment and your first real fitting job, on a shape that is forgiving because it goes over a jumper.
- Wool coat, 2.5–3.0m, £2.50–£3.00 at £1/m. Tailoring, interfacing, lining, pressing. Do not start here, but do not be frightened of it either — at these prices, a failed first coat costs less than a takeaway.
If you are unsure which fabric suits a pattern you already own, the pattern envelope usually names suitable fabrics on the back. That list is worth more than any blog post, including this one. For the general method, see choosing the right fabric for your project.
Layering: matching a lining to a heavy outer
A lining does three jobs. It lets a garment slide over your clothes, it hides the seam allowances, and it adds a thin layer of trapped air. It should always be lighter than the outer fabric — usually a lot lighter.
| Outer fabric | Outer GSM | Suitable lining | Lining GSM | Why |
|---|---|---|---|---|
| Needlecord pinafore | 190–260 | Cotton lawn or poly lining | 60–100 | Stops the cord catching on tights |
| Tartan skirt | 200–260 | Anti-static poly lining | 60–90 | Stops cling and seating at the back |
| Jumbo cord jacket | 330–450 | Poly satin or viscose twill | 80–120 | Sleeves need slip to get an arm through |
| Wool coat | 450–600 | Poly satin, or fleece for warmth | 90–200 | Fleece lining adds real warmth but bulks the seams |
Two practical rules. First, buy the lining at the same time as the outer, and buy the same metreage or a fraction less, a lining is cut from the same pattern pieces minus facings, so for the pinafore above you need about 1.6m of lining against 1.8m of cord. Second, do not line a fleece garment. Fleece is already warm and already bulky, and a lining inside it produces something that will not fit under a coat.
If you want warmth without bulk in a coat, a fleece lining at 200gsm inside a 450gsm wool outer is genuinely warm and costs about £2.00 in lining at an indicative £1/m for 2m. Grade your seam allowances hard at every intersection or the coat will not press flat.
Autumn colour without buying a new wardrobe of fabric
You do not need eight new shades to make a wardrobe read as autumn. What shifts the season is contrast and value, not hue. Three approaches, all cheap.
Change the base, keep the accents. One or two metres of a deep, muted base colour — rust, olive, ink, oxblood, charcoal — will make everything you already own look seasonal by sitting underneath it. A 1.5m elasticated skirt in a rust needlecord is £1.50 at an indicative £1/m and does more work than five new tops.
Use texture as the colour. A jumbo cord in plain camel reads as far richer than a flat cotton in the same shade, because the ridges throw shadow. Same dye, same price bracket, entirely different effect. This is the cheapest trick in autumn dressmaking and it is covered further in fabrics that look expensive but are not.
Let tartan do the work. A single check brings in three or four colours at once, so one tartan make ties together several plains you already have. Pick a tartan whose ground colour matches something in your wardrobe and the rest follows. Half a metre for a scarf, at 50p at an indicative £1/m, is the lowest-risk way to test whether a palette suits you.
One last piece of arithmetic. If you sewed every make in the table above — pinafore, trousers, shirt, throw, four scarves, lined skirt, hoodie and four cushion covers — you would need 14.5m of fabric plus 1.0m of lining. At an indicative £1/m that is £15.50. At £3/m it is £46.50. Work out your own totals before you order, using how much fabric you need, and buy the whole autumn in one delivery rather than five.
Frequently asked questions
What fabrics are best for autumn sewing?
Corduroy, brushed cotton, wool coating, polar fleece and tartan cover almost everything you will want to make. Brushed cotton is the easiest to sew, fleece is the warmest for its weight, wool coating is the warmest overall, corduroy is the hardest wearing and tartan is the one that reads as autumn without any effort on your part.
What GSM is warm enough for a coat?
For a proper winter coat, look for 400gsm or more; classic melton and heavy wool coatings typically sit between 450 and 700gsm. Around 300 to 400gsm gives you an autumn jacket or overshirt rather than a coat. These are typical figures — GSM varies by supplier, so check the listing before you buy.
Is corduroy or wool warmer?
Wool, at equal weight. Wool fibre crimps naturally and traps air right through the cloth, while corduroy traps air mainly in its surface pile and is usually cotton, which conducts heat away faster. A 450gsm jumbo cord is a genuinely warm trouser fabric, but a 450gsm wool coating is warmer again.
What can I sew for autumn in a weekend?
A fleece throw, a fringed tartan scarf, a set of cushion covers or a simple elasticated skirt. A 150 x 200cm fleece throw needs 2m and no hemming at all. Four fringed scarves come out of 1.8m of tartan cut lengthwise — at an indicative £1 per metre, that is 45p a scarf.
How much fabric do I need for a pinafore dress?
On 150cm-wide fabric, allow 1.8m for UK sizes 8 to 14 and 2.1m for sizes 16 to 24. If you are using corduroy or velvet, keep those figures — they already assume a one-way nap layout. At an indicative £1 per metre that is £1.80 to £2.10; at £3 per metre, £5.40 to £6.30.
