Extra wide 100% cotton muslin in a better weight than most. It's ideal for mockups, toiles, and crafts. 100 to 140gsm are common weights for muslin, but ours is a nice 160 grams per square meter. In our tailoring shop, we also use this muslin for covering our pressing table and sleeve boards. 63" (160cm) wide.
This fabric is now included in our Interlining Sample Book (even though we don't use it as an interlining!).
