Olivia & Oliver Fibers is a Netherlands‑based indie yarn brand specialising in beautifully hand‑dyed yarns and fibre dyed with artistic care in their Amsterdam studio.

The company was founded in 2019 by Tam, a Californian maker who combined a lifelong love of knitting and colour theory with a passion for fibre dyeing, turning that creative devotion into a thriving, globally‑loved yarn business.

Their extensive range includes classic sock, merino fingering, DK, worsted, organic merino, tweed bases, and luxurious suri silk, offering makers a wide variety of natural fibres and textures to suit every project and style. With fresh colourways introduced regularly and options for dyed‑to‑order or sweater‑quantity dyeing, Olivia & Oliver Fibers appeals to knitters and crocheters seeking expressive, hand‑crafted yarns that bring personality and depth to handmade garments and accessories.
