If a handkerchief is made of a single thread how long would that thread be?

The length of the thread used to make a handkerchief depends on its size, thickness, and weave pattern. A standard handkerchief measures about 16 to 18 inches square, and if we consider an average thickness of the thread, it could take several hundred feet of thread to create the fabric. Ultimately, the exact length would vary based on these factors, but it would likely be in the range of several hundred feet.
