A fabric generally made of multiple yarns, high twisted wool and has a plain weave. The high twist allows for an open weave, which makes the fabric very airy in the sense that you can feel any breeze. Also, due to its high twist, it has a rather coarse feel to it and a rather hard touch. At the same time, this makes for a very dense and durable fabric. Nowadays, fresco weights range from 8oz€“15oz per yard (248g€“465g per metre)
