I was looking spring fashion and found a jacket made from technical twill. I am sure your first thought is the same as mine "What is technical twill". Looking at the description it is a polyester twill. In my sesrch for technical twill, I found an interesting article about twill that disgusses the characteristics, properties, and uses of twill. It is well worth reading to understand twill better. Yes, it does talk about "technical" twill and it is not a special fabric. So, the only reason the jacket was $1300 is that it had an interest cut and yeah, no similar patterns. Oh, to be a pattern designer. Hope you enjoy the article.
Happy Stitching!
