Arced - Yeah, actually i think for long hours about that. We do two seperate styles of seven-fold, a traditional 7 with no liner and the Double-4 design which we've tweaked and modified some with each iteration. Anyway I recently did an evaluation of about 8 different liners and cut open some 'expensive' ties to see what they were using. Surprisingly, a lot of folks are using synthetic liners these days (shocking I tell you, shocking.). For an unlined tie you have to be very certain to use the correct silk weight - I screwed that up on a few of my early ones. On the double 4 you have to be sure not to get the tie too thick - you also have to use a very high quality wool liner. We have one of each of our ties always knotted for dressing mannequins and hanging on a hook in my workroom - a terrible sin I know (You should always untie your tie, not by YANKING the loose end but untie it carefully by reversing the tying process) Here is why the lining is critical - the synthetic ones and cheaper wool ones will get distorted - synthetics tend to warp from heat, cheaper wool liners will shrink or fall apart. A properly made premium wool liner will form a smooth, beautiful crease that even after several months will release to it's former state with a little steam. As to thoughts about knots, on a more serious looking tie I will make sure that it can be tied tightly so that below the knot it comes outward ever so slightly before 'breaking' downward. For something like the 65/35 cashmere/silk blend I've been experimenting with I envision a slightly less formal, looser knot and built that accordingly - but I wanted that one to be somewhat substantial and thick anyway :-) Thanks for a good question. From my side the answer is to keep checking with customers and keep tweaking the product until I, and they, are satisfied.
