For ties a good wool interlining is very important - there used to be a number of luxury wool interlining tie weavers in Italy but the number is dropping to only a couple now. Cheap wool interlinings are still available both from China and Italy - but they are just that cheap - they don't drape well at all.
England and America had some weavers but mostly polyester or a mix. Today we use the best Italian pure wool interlinings in the world, made by Tata Stoppani in a small factory in Como in the north of Italy. Her father Bruno started the firm in the late 1950's, coincidently around the same time the Sam Hober Company was created in New York by my father Mark Hober. Tata, is the rare mix of someone with technical skills and great people skills - it is a pleasure working with her and her team. Her wool interlinings use the best wool; but it is her team's finishing skills that bring out the best in her interlinings.
John asked today about the possibility of an unlined satin tie. It is possible but I am reluctant to make an unlined satin as the drape does not tend to work well. Satin works best with a classic wool interlining.
Cetin asked about "what happened to burgundy silks?" We still have solid burgundy silks but sometimes there are color variations from one roll of silk to another (my apologies - nothing we can do about this...) and burgundy is often confused with maroon. Burgundy is similar in color to a Merlot or Bordeaux wine and is a mix of red and purple while maroon is a mix of red and brown.
