De Rerum Natura – Gilliatt


The perfect work horse yarn and a YAK team favourite, Gilliatt is soft and bouncy woollen spun yarn made from a blend of French and Portuguese merino wool. It has a good stitch definition and a sticky handle which makes it suitable for all sorts of projects. Cables, stranded knitting, lace, you name it Gilliatt can do it all and do it all with style. Like all woollen spun yarns it is lofty and warm. It is soft to start with and becomes even softer after washing. A great choice for cosy winter jumpers which will get a lot of love. ⁠

De Rerum Natura is a wonderful French brand specialising in the production of European merino yarn. Sustainability and transparency are at the heart of the company’s ethos and this translates into every aspect of their business practice.

50% of their merino wool comes from certified organic flocks raised by transhumance – an ancient practice in which flocks are moved from one grazing ground to another following a seasonal cycle. The rest of their fleece is sourced from small traditional farms chosen for their respect for animal welfare.

Their yarn is spun and dyed in a small mill in Rougnat, France. The mill uses a phyto-purification system to filter their water as well as dyes that are compliant to the norms set by REACH – an EU organisation in charge of regulating the use and production of chemicals in manufacturing.
