I've noticed the trend toward narrower ties. (I was quite surprised to see Hawes and Curtis offering a wide fashion tie line recently.)  All of my ties are in the 9 cm range.  To what width are you taking the main range of ties?

I've also noticed a trend toward smaller collars as well e.g. Hugo Boss and Ben Sherman to name a few. I appreciate TM Lewin's focus on classic collars.  Do you have plans to reduce collar sizes as well?

Hmm...it's generally accepted that a tie-knot looks balanced in the space created at the collar spread if the knot occupies a third of that space. However, fashion does what fashion does, and fashion breaks the rules creating trends that people will follow. (Trends can last from between 3 and up to 10 years.) Depending on whether your personality can 'carry off' the more outlandish rule breaking or trend, will determine if the wearer looks like a fashion victim or fashionably stylish. Everyone has a style appropriate to them as an individual and it follows that not everyone can carry off all the trends.

There are 4 basic knots that a man needs to know to get him through life although Thomas Fink and Yong Mao researched tie knots and created 85 ways to tie a tie. (If you're interested in that kind of detail!)

The 4 basic knots I would recommend would be The Windsor, The Four-in-Hand, The Half Windsor and a knot called The Custom Shop Knot. This last knot is very useful especially as it always remains soft however tightly it is pulled.

The most impressive tie knot a man can learn is The Bow Tie - even if he only uses it once.
