National Flannel Day

National Flannel Day is an annual American holiday celebrating flannel—a fabric that remains incredibly popular today. Checkered flannel shirts, in particular, have won the hearts of millions. The holiday is observed every year on February 10.

History

The exact origins of flannel are unclear, but it’s believed the fabric began to spread in Wales during the 16th century. Originally called “Welsh cotton,” this name was misleading, as true flannel was made from coarse wool.

In the 19th century, industrial production of flannel in Wales increased rapidly. The fabric was used to make undershirts during the Civil War because of its durability and warmth. In the early 1900s, flannel trousers became popular, especially among cricket players and other athletes. During both World Wars, flannel was widely used for undershirts and jacket linings.

National Flannel Day was established in the 2000s to honor this versatile fabric, which remains a staple in fashion today.
