Oh, is that right? That's interesting. So with a grenadine, you have a silk shell as with a regular woven (but smooth) tie and an interlining of wool as with a standard tie--the only difference being that the shell is a good deal heavier (and honeycombed as noted by aportnoy). I had thought of them as akin to a knit tie, as you suggest. Tomasso, thanks for the link from David Hober. I had actually seen that--it's really good isn't it.
