Perhaps my favorite neckties are those made from silk grenadine. Grenadine is a woven silk that makes a finer, and so more formal, version of a knit tie. Most of the world's grenadine is made by an Italian mill, Fermo Fossati, where old shuttle looms weave stuff that literally cannot be made with modern high-speed equipment.
To my surprise, I learned recently that Fossati weaves two types of grenadine, the more common being the honeycomb patterned Garza Grossa in the first photo that is used for neckties by makers including Michael Drake and Sam Hober (David Hober provided the formal names for the two weaves).
The other weave, Grenadine Garza Fina, is finer, and more suitable for patterned neckties than the Grossa. It also makes an interesting solid tie on its own - still textured but more mannered than the larger weave.
And that is the second type of grenadine.
