MeiSi Super Fine is the ultimate linen thread, especially suitable for hand stitching. The twisted strands create a strong thread that is protected against deformation and stretching. The round, smooth thread also reduces friction when stitching, which is comfortable and ensures a better result. Finally, the patented click coil ensures that you can keep the thread ends tidy. Some leatherworkers also use MeiSi Super Fine as a machine thread.

MeiSi Super Fine linen thread is available in 97 colors and 4 thicknesses: M30 (0,35mm), M40 (0,45mm), M50 (0,55mm) and M60 (0,65mm). Order your desired color and thickness of thread in a mini or medium spool. Are you looking for a different MeiSi thread color? Contact us for the possibilities.
