A metal label on a beanie, jumper or hoodie is one of the quickest ways to make knitwear look premium. The trouble is that knitted and stretch fabrics behave nothing like denim or leather: they stretch, they sag, loops can run, and with swimwear you add chlorine and salt. A label that sits perfectly on a jacket can drag a fine knit downwards or corrode after one summer. This article is laid out as a list of problems and fixes, garment by garment.
The core issue: weight vs fabric
Metal labels are typically 0.5–1.2 mm thick, with 0.7–0.9 mm the sweet spot for most clothing. A zinc alloy label of 30 x 8 x 1 mm weighs roughly 1.5–2 g, while one of 50 x 15 x 1.5 mm is already around 7–8 g. On a heavy 350 gsm hoodie that is no problem; on a fine 180 gsm merino knit a large label causes visible sagging.
| Item | Suggested size | Thickness | Fixing |
|---|---|---|---|
| Beanie | 15–25 x 4–6 mm | 0.6–0.8 mm | Sewn through holes |
| Fine jumper, cardigan | 15–20 x 4–5 mm | 0.5–0.7 mm | Sewn, on reinforcement only |
| Chunky knit | 20–35 x 5–8 mm | 0.7–0.9 mm | Sewn |
| Hoodie, sweatshirt | 25–50 x 6–15 mm | 0.8–1.2 mm | Sewn, or prongs with a backing |
| Swimwear | Small only, 10–20 mm | 0.5–0.8 mm | Sewn in a non-stretch zone, or on a ring or buckle |

Problem: a ladder starts around the label
An ordinary sharp needle can split the yarn and start a run. Fix: sew with a ballpoint needle, which pushes the loops aside instead of cutting them. Go between the yarns, not through them.
Problem: the label sags and drags the knit
Fix: on the inside, behind the label, place a small piece of knit fusible interfacing or firm fabric, 5–10 mm larger than the label on every side. Sew through it so the weight is spread.
Problem: the area around the label won't stretch
Choose a spot where the knit stretches least – close to the rib at the hem or cuff rather than in the middle of the chest.
Beanies: small size, right spot
On a beanie with a turn-up, the label goes on the cuff, centred at the front or slightly to the side. The key decision is whether to sew through the outer layer of the cuff only, or through both:
- Outer layer only – the cuff can still be unfolded, but the label must be light.
- Both layers – stronger, but it fixes the cuff and the hat loses flexibility.
Sew the label on before the cuff is turned, while the knit is flat. Choose rounded corners – a sharp corner on a hat scratches the forehead. Small labels of 1.5 x 0.5 cm or 2 x 0.4 cm suit beanies well.
Hoodies and sweatshirts: where a big label works
Heavy fleece (300–400 gsm) can carry a larger label – on the chest, the kangaroo pocket, the sleeve or the hem. Watch out for:
- Friction – hands constantly rub across a label on the kangaroo pocket; choose rounded edges.
- Washing – turn the garment inside out and wash at 30–40 °C; metal knocks against the drum.
- Prongs – if you use them, always with a backing plate and an inner tape, because fleece is worn against the skin.
Swimwear: chlorine, salt and heat
Swimwear is the toughest case. Pool chlorine and sea salt attack both the plating and the base metal; zinc alloy with thin plating can grow white oxide within a single season. In the sun, metal heats up and can feel unpleasantly hot on the skin.
- Prefer stainless steel or well-lacquered finishes tested in chlorinated and salt water.
- Keep it small and away from high-pressure areas.
- Often the better answer is to brand the functional hardware instead: the buckle or the strap ring.
- Ask for low nickel release – swimwear is in prolonged contact with wet skin.
Our buckles collection includes small gunmetal styles made for clothing, swimwear and footwear, and our rings range has polyester rings for swimwear that won't corrode.
Thread and stitch
On knits, the thread has to work with the fabric too. Polyester thread is stronger than cotton and won't rot in damp conditions – important for swimwear. Hand sew with 3–4 passes through each hole and don't pull too tight: if you tug the thread hard, the knit gathers around the label and forms a dip. On a machine with a zigzag stitch, the label needs holes at the ends and must be sewn very slowly so the needle never strikes the metal.
A label, or something else?
Sometimes a metal label simply isn't the right tool. On very fine knits, babywear and underwear, a soft woven or satin label is the better choice: it weighs nothing, doesn't scratch and won't react with chlorine. Metal is strongest where the fabric is dense and the garment is seen from a distance – sweatshirts, chunky knits, beanies.
Quick checklist
- Label weight against fabric weight.
- Reinforcement behind the label on every knit.
- A ballpoint needle and a thread with some give.
- Rounded corners wherever there is skin contact.
- A finish tested for chlorine and salt on swimwear.
- Care instructions – inside out, low temperature.
Labels for laser branding
In our labels collection Bul-tex offers small E-series metal labels for laser engraving a logo – from 1.5 x 0.5 cm to 3 x 0.8 cm, in nickel and gunmetal, with a minimum order of 100 pieces. The small sizes are ideal for beanies and knitwear. For labels in your own shape or in stainless steel, get in touch. More on woven labels for knitwear is in the Labels section of our blog.
