Cloth of the Pharaohs
Muslin sometimes is made from other fibers. "The weave of linen muslin was so fine that the Egyptian Pharaohs used it for wrapping mummies," Fabrics Manufacturers says.
Clothing sometimes is made from muslin. However, it is used more often by dress and costume makers to perfect patterns before applying them to expensive fabrics. The costume website Alley Cat Scratch says that is why garment mock-ups are referred to as "muslins."

The quilt-making website Connecting Threads details a method for using muslin as a base for crazy-quilt blocks. It notes that this "makes the block more sturdy" and eliminates the problem of sewing onto paper backing that must be torn away.
