Cotton threads are a true classic – made of 100% natural cotton, strong yet beautifully elegant. Thanks to the mercerization process, they have gained a subtle sheen, increased durability, and better dye absorption, making them perfect for fabrics intended for dyeing. Suitable for both machine and hand sewing, they are especially recommended for natural fabrics such as cotton and linen – ideal for hemming, joining elements, or making alterations. The 12 x 3 specification makes them a reliable choice for sewing bed sheets, face masks, or everyday clothing.
