De Rerum Natura Ulysse


A breed specific, sustainably produced yarn from France…available exclusively from fibre space.

Categories: ,


Ulysse is a woolen yarn of soft white french (Mérinos d’Arles from Provence) and black Portugese Merino (Merinos Petra from Alentejo Valley) produced in France in an ecological way.

De Rerum Natura yarns are spun semi-woolen. You may be familiar with the lofty twist of woolen spun yarns like Brooklyn Tweed Shelter or Loft, but this method is not ideal for merino wool. In order to still produce a lofty yarn, Solenn convinced the mill operator in Creuse, France to combine combed and uncombed fibers into the airy finished product. While the yarns look rustic, they still have the softness we all know and love from Merino.

The dyeing process varies from color to color, ultimately creating a beautiful rainbow to choose from. Black and white fibres are mixed together to give the finished yarn a slightly heathered appearance, but these yarns aren’t just limited to the natural shades. Some colors are dyed after spinning, while others begin with dyeing the white wool before spinning. Regardless of the method used, great care is taken to ensure that the dyeing products used are as environmentally friendly as possible with the mill using plants as a natural water recycling system to further reduce environmental impacts.

We recommend handwashing in warm (not hot) water with gentle soap. Lay fabric flat to air dry.
