Acrylic and polyester yarns are synthetic fibres that offer practical advantages distinct from natural fibres. Their primary characteristic is machine-wash resistance: unlike wool, which can felt or shrink, a quality synthetic yarn retains its shape, dimensions, and colour after many wash cycles. This makes it particularly recommended for projects intended for frequent everyday use, such as baby blankets, children's garments, regularly worn accessories, and household items that are washed often. Synthetic fibre is also available at an accessible price point, making it advantageous for large projects that require several skeins, such as blankets and throws. The available colour range is generally very extensive, with strong colour stability over time and no risk of fading in the wash. The selection covers all weights, from fine yarn for amigurumi to very bulky yarns for fast knitting, including medium weights for everyday garments and accessories. Some synthetic yarns also offer special texture effects, such as fleece fibres for a plush finish, halo yarns, and loopy yarns for expressive textures.
