There have been many interesting things that I have discovered about men's neckwear in my tie research. I found things out mostly because I was curious, but sometimes it was an accident just so I could have more to say about my ties than,"this tie stinks," or "this tie is awesome."
For example, I always wondered why so many ties have diagonal designs going across them. Originally, I thought that it was part of the overall men's wear thing. A diagonal to offset the pinstripes in a suit or the vertical lines in a shirt. It seemed logical, but it was completely wrong.
When woven fabric is cut across the grain, or on the bias, it is cut at a 45 degree angle related to the vertical thread, or warp, and its horizontal thread, or waft. The reason that tie fabric is cut in this manner is so the tie will come out of the knot evenly without twisting. If the pattern on the tie fabric is a woven pattern, such as stripes, when the fabric is cut on the bias and a tie is created the pattern will become a diagonal pattern.
Now the problem with this new found piece of information is that doesn't explain ties with a diagonal slant that are prints, such as the tie I wore on Tuesday. Maybe Countess Mara is just messing with my head.
