Choosing a yarn fibre

The fibre changes how a project wears, washes and feels in the hand, often more than the colour or brand.

FibreCharacterBest forWatch out for
CottonNo stretch, absorbent, holds its shape, cool to wearCoasters, bags, baskets, amigurumi, dishcloths, summer topsCan be hard on hands, heavy when wet, may split
WoolElastic, warm, springs back, blocks wellHats, sweaters, blankets, cosy accessoriesCan itch on some skin, may need hand-washing, may felt
AcrylicLight, affordable, colourful, machine-washableToys, blankets, projects that get lots of washingCan pill, does not breathe, melts under a hot iron
LinenCrisp, strong, drapes and softens with ageMarket bags, table runners, summer garmentsStiff at first, less forgiving of loose tension
Blends (wool/cotton, cotton/acrylic, bamboo)Combine strengths of their fibresBaby items, garments, anything that needs easy careCheck the care label; blends behave differently in the wash

A short guide

  • For shape (bags, baskets, amigurumi): choose cotton or linen, in a tight-plied yarn.
  • For warmth (hats, blankets): choose wool or a wool blend.
  • For babies: choose a soft, machine-washable yarn. A cotton or cotton-acrylic blend is a safe choice.
  • For learning: choose a smooth, light-coloured worsted yarn, so the stitches are easy to see.
