Sinamay is one of the most popular hat-making foundations in the world. It is woven from the processed stalks of the abaca tree, a banana palm native to the Philippines. Abaca fibre is three times stronger than cotton or silk, and a fabric made from 100% abaca can last for over 100 years. As a result, sinamay holds a very firm shape. Because it is a natural fibre, it holds colour beautifully.
