Burn Holes in Clothes – How to Judge and Repair Them

Why a burn hole is different from a tear

When an ember, spark or hot iron hits the fabric, the fibres are destroyed by heat – they do not burn away to nothing, but stay as a brittle, black or melted rim around the hole. This edge is 'dead': it is fragile, it will not hold stitches, and the black is charred fibre that does not wash out the way ordinary soot does. A clean cut or an abrasion hole has sound fabric right up to the edge; a burn hole has a zone of damage around the opening itself. That is why the repair always starts with clearing away the burnt material – not with closing the hole.

Synthetic or natural fibre? The edge tells you

What the fabric is made of decides both how the damage looks and what is possible:

• Synthetic fabrics (polyester, nylon, acrylic, fleece) melt. The fibres shrink into a hard, shiny bead or a stiff rim around the hole. This melt cannot be 'melted back' – it must be trimmed away, and the glossy rim often remains.
• Natural fibres (cotton, wool, linen) char. The edge goes brittle and black like ash, but without the hard melted rim. Around a small hole in a woven natural fabric, an invisible repair is easier than in melted synthetic.
• Blends behave like their most heat-sensitive fibre – a little melting and a little charring mixed together.

First step: clean away the burnt fibres

Whatever the fabric, the first move is to remove the damaged zone gently, so you have sound fabric to work against. This makes the repair both stronger and neater.

1. Lay the garment flat on a hard surface in good light.
2. Scrape or trim away the loose, charred or melted edge with small scissors or a blunt blade, until you reach sound fabric. Take as little as possible.
3. If black soot has settled around the hole, lift it rather than rub it – rubbing pushes the carbon into the fibres.
4. Reassess the hole once the edge is clean: is it a tiny dot, a larger opening, or mostly a discoloured scorch mark with no hole?

Small burn holes versus larger damage

The size of the cleaned hole decides the method. Small holes in woven fabric can become almost invisible; larger holes are solved with a patch.

• Tiny dots (spark or cigarette holes) in woven fabric can be closed with fine darning or rewoven threads – ideally thread taken from a hidden seam or hem so the colour matches. This is fine, patient handwork.
• Larger holes are best covered with a patch: from behind with dense darning for a discreet result, or a visible patch on top where it suits the style.
• In knitwear a small burn hole can often be darned or masked with a duplicate stitch in the same yarn, while a larger hole needs a set-in patch.

Scorch marks without a hole

Sometimes it is not a hole but a discoloured scorch mark – typically from an iron that was too hot. Then it depends on the fibre: on synthetic fabrics a shiny, glassy mark means the surface has melted, and that sheen is unfortunately permanent. On cotton and linen a light, brownish scorch is often just surface damage; it can sometimes be faded with repeated washing, air and sunlight, while a deep, dark scorch means the fibres are damaged and the colour is there to stay. Feel the fabric – if it has gone stiff, brittle or papery in the mark, the damage is more than cosmetic.

Send the garment to us

If the burn hole is small and you want it as invisible as possible, it sits somewhere visible, or you are unsure about the fabric and fibre, you can send the garment to us. We assess the damage and repair it according to the garment and fabric, aiming for a discreet result where possible. You order online from anywhere in Norway, and you see the price before you order.
