Pills or bobbles are excess fibers that rise to the surface of certain textiles. They typically appear where there is frequent abrasion on the fabric, like on the armrest of a sofa or the sleeve of a wool coat. Pilling is a natural process that will inevitably happen to even the most luxurious fabrics like cashmere wool and is not necessarily an indicator of poor quality, nor a reason to discard or return a garment.
