Just to pick up on Grimslade's helpful comments on seven-fold ties, it's worth mentioning that the thickness and stiffness to which he refers is really mostly a function of whether or not the tie is lined. There are lined and there are unlined seven-fold ties. The lined ones do tend to be pretty hefty, but the unlined ones can actually be less so than a lined traditionally-made tie. Another point worth making, I think, is that the term "double four-fold" is, as far as I know, used only by Chuck Franke to describe the way in which his Carlo Franco ties are made. Finally, the term "seven-fold" is used a lot in tie marketing to refer to ties that aren't actually folded seven times. In fact, as far as I can tell, many ties that have five and six folds are given this designation. As an example, I have a lined Kiton "seven-fold" tie that--as far as I can tell (and I've looked hard)--has a total of six folds.
As for the CT ties, I have no first-hand experience. If I had to guess, I'd say that the quality will be decidedly second- or third-tier, and nowhere near that of Kiton, Attolini, Borrelli, Carlo Franco, Mulberrywood, Charvet, Breuer, Drake, Marinella, T&A, FIHTies, and several other makers. I'm making this assumption on the basis of the quality level of CT goods in general--which is, in most cases, decidedly second-rate.
