Have you ever noticed those lines running across your bath towels and wondered why they’re there? Recently, this seemingly small detail sparked a wave of curiosity on social media, with thousands of people joining the discussion. While it might seem trivial, the answer reveals some clever design behind an everyday household item.
Those lines, called “dobby borders,” are much more than decorative. Their primary purpose is to strengthen the towel, helping it resist fraying even after repeated washes. The dobby border also maintains the towel’s structure, preventing the edges from becoming too thick or bulky. This allows the towel to remain soft, lightweight, and efficient for drying, balancing comfort and performance.
