This allows them to fall straight after the knot has been tied, without curling. A simple test consists of holding a tie across you hand. If it begins to twirl in the air, it was probably not cut on the bias and it should not be purchased. Originally, neckties were cut from a single large square of silk, which was then folded seven times in order to give the tie a rich fullness. Today the price of silk and the lack of skilled artisans prohibits this form of manufacture.
Ties now derive their body and fullness by means of an additional inner lining.
Besides giving body to the tie, the lining helps the tie hold its shape. The finest-quality ties today are lined with 100 percent wool and are generally made only in Europe. Most other quality ties use a wool mixture. The finer the tie, the higher the wool content. You can actually check.
