Thanks for the replies everyone.
I forgot to mention that I actually have 9 ties so far from JaanJ.
I'm looking for more variety.
But thanks anyways.
I'm also looking for non-silk pocket squares if anyone can help.
Cotton and linen squares are fairly ubiquitous. Most any well-stocked quality men's store should have some. Linen squares seem to be more common prior to the spring and summer seasons. One can always fold a good-quality white cotton handkerchief and use it as a square, but linen seems more classic and preferable (although I have a good many more cotton than linen squares).
