Which of the following is a disadvantage of linen fabric?

Linen fabric is known for its strength and breathability, but one of its notable disadvantages is that it frays easily. This can be an issue during the sewing process or when the fabric is subjected to wear and tear. Fraying occurs because of the way the fibers are woven and the inherent properties of the cellulose fibers in linen, which can be less stable than those in other fabrics. Consequently, unfinished edges may require additional finishing techniques to prevent fraying, making garment construction and maintenance a bit more challenging.

The other options reflect characteristics that are not disadvantages. Colorfastness indicates that the colors of the fabric remain vibrant and do not fade or bleed, which is a beneficial quality. Heat resistance suggests that linen can withstand high temperatures without damage, making it a good choice for items like tablecloths or summer attire. Wrinkle resistance, however, does not apply to linen, as this fabric is naturally prone to wrinkling, but the other options indicate qualities that are advantageous rather than disadvantages.
