De Rerum Natura is a respected French yarn brand founded in 2012 by Solenn Couix‑Loarer with a mission to offer makers ethically sourced, traceable, and beautifully crafted fibres. The name, meaning “the nature of things,” reflects the brand’s deep focus on natural materials, transparency, and respectful relationships with the land and animals that provide the wool.

At the heart of De Rerum Natura is a commitment to sustainability and responsible production: their yarns are made from merino wool sourced from carefully chosen French and European farms where sheep are raised with care and never subjected to mulesing, and the fibres are spun and dyed in Europe using environmentally conscious processes.

Celebrated for timeless colours, authentic texture, and versatile performance, De Rerum Natura yarns offer makers natural, heirloom‑quality materials that feel as good to knit with as they do to wear. Whether for cosy garments, delicate accessories, or enduring wardrobe staples, the brand appeals to craft lovers who value slow fashion, mindful making, and yarn with a meaningful story.
