Linen thread is a type of thread made from the fibers of the flax plant. Known for its strength and durability, linen thread is often used in sewing, embroidery, and crafting. It has a natural luster and a slightly coarse texture, making it ideal for projects that require a sturdy finish. This thread is also valued for its ability to hold shape and resist fraying. Unlike synthetic threads, linen is biodegradable and environmentally friendly. It is available in various thicknesses and colors, allowing for versatility in different applications, from textiles to bookbinding.
