100% cotton Shetland flannel from Robert Kaufman. Beautifully soft on both sides with great drape, it is perfect for dressmaking such as dresses, skirts, trousers and jackets. It has a bit of weight, but not too much. It would make a lovely Sapporo coat.
The second photo is not representative of the colour of the fabric (which is navy with a hint of royal blue in the pattern of the herringbone) but is shown to demonstrate the herringbone pattern.
