Superwash & Cotton wool/scarf/wrap
Although superwash yarns and cotton are, in theory, washing-machine safe, I still suggest you hand wash in cold water and lay flat or rinse and spin and then lay flat/block to dry. A wool soak like Eucalan is highly recommended.
If exposed to heat and agitation, your wool/scarf/wrap will felt, so be sure to hand wash gently in cold water (a wool soak like Eucalan is recommended) and dry flat.
Although all of the yarn is washed, and then rinsed and soaked in Eucalan after it is dyed, it is recommended that you wash the yarn/finished product separately, as colours may still bleed on first wash.
