Calais cocoons are made of three strands of twisted mercerised cotton. They are presented in small cocoons of 5 grammes (approx. 110 m) making them pleasant and easy to use.
Calais cocoons comprise three strands (professionals use the term "ply" for strand). The thickness corresponds to a N°80 from DMC. All the colours can be bought individually or in boxes of 12 per same colour.
Calais cocoons can be shipped via the cheaper letter rate, rather than parcel rates. This is only possible if the order contains products that benefit from this tariff. The cost is automatically calculated on the site and proposes the two options.
