I spoke to them about making that exact tie a few weeks ago. They sent me a sample of the material to see how it compared to the grosgrain which I was looking for to match my tux. it is very nice, ribs are not as pronounced as the tux which I was hoping for. It is certainly on my list of choices and think it would make a great addition.
If you end up buying one, please snap a few picture and post them.
I'm glad you shared this website. My tux is grosgrain, and I have a Blace Fleexe BB straight batwing bowtie that I like, but I am really liking the texture of the black pique bowtie. Thoughts?
Personally, I think the cotton pique is too informal (if nice) looking. Upon closer inspection, I can see that the grain of Cordial Churchman's faille is too subtle (as noted by Brianpore).
