Cotton yarn: how to choose it

Cotton is a plant fibre, not an animal coat: no lanolin, rarely any prickle, a cool dry hand. It takes dye calmly, keeps its colour through washing, and holds a stitch cleanly. That is why baby vests, crochet and summer tops so often come from cotton. The whole range sits in the cotton category; here is how to find your way in it.

What cotton does well

Cotton breathes and absorbs moisture without feeling wet, so it behaves in heat better than most fibres. It is also dense: the same meterage weighs more than wool, and a finished piece has a firm drape.

The thread has little spring, so ribbing recovers slowly and fabric can relax with wear. A swatch, washed and dried before you cast on, tells you how much. What cotton will not do is felt in the wash or grow a halo: stitches stay crisp, and hard-wearing everyday pieces are its home turf.

Pure cotton or a blend

A classic pure cotton such as Mayflower Cotton 8/4 is the workhorse for dishcloths, baby garments and summer tops: 100% cotton, 170 m on a 50 g ball, 3 mm needles. It machines at 60 °C, a cycle wool never enjoys.

Blends adjust the character. A share of lyocell adds shine, drape and a cooler hand: Kremke Morning Salutation VEGAN is 51% lyocell and 49% cotton, 110 m on 50 g, fine enough for shawls and airy knits. A few percent of polyester buy strength and shape: Erika Knight Gossypium Cotton Tweed is 96% cotton with 4% polyester, a DK at 125 m per 50 g, and the little flecks read well in plain stockinette.

Babies and crochet

Because cotton carries no lanolin and rarely irritates, it is a first pick for newborn knits and for skin that objects to wool. Crochet benefits twice: a firm, inelastic fabric keeps its shape, and the crisp stitch definition makes textured motifs and little toys read as drawn.

Whatever you choose, shop by the band rather than by habit. Composition, meterage and care facts live on every product page.

Weight and season

Fine and sport cottons earn their keep in summer: tops, tees, market bags. DK and heavier cotton carries spring and autumn easily, and in winter a cotton base layer under wool regulates heat without the prickle that some skins feel from wool worn straight on. If warm-weather knitting is your season, the summer yarn guide compares cotton with linen and silk blends in detail.

Knitting and care

Cotton shows every stitch, so even tension pays off twice. On a large piece, circular needles spare your wrists the weight. Wash by the band: cotton ranges from 30 °C delicates to the 60 °C cycle of Cotton 8/4. Dry heavy pieces flat so they keep their shape.
