A Yarn with a Story
 
Alga is a tribute to nature’s innovation. Made with SeaCell, a silky-soft fibre derived from sustainably harvested seaweed, this yarn blends modern science with traditional craftsmanship. The result? A breathable, self-striping yarn with a smooth hand feel and a subtle sheen that brings effortless elegance to your summer makes.
 
The SeaCell content doesn’t just sound impressive — it adds skin-friendly properties and environmental value, while the organic cotton and bamboo viscose bring structure, softness and flow. Together, they create a yarn that honours nature while elevating your craft.
 
Each skein reveals gently shifting stripes that add visual interest without overpowering your stitchwork. With great stitch definition and a naturally cool touch, Alga is a dream fibre for warmer weather.
