Cose Bias Tape, 40mm wide and in blue, sold by the meter, is a fabric tape cut diagonally along the grain, giving it enough elasticity to follow curves and corners. It is used to finish and protect the raw edges of sewing pieces, such as necklines, sleeve openings, and hems. The 40mm size, wider than the 25mm reference, is suitable for thicker fabrics or for those who prefer a more generous finishing margin. The blue color is a versatile choice for pieces in cool tones or as a contrasting decorative element. Because it is sold by the meter, it allows you to cut exactly the length needed for each project.
