This is a medium weight very stiff cotton canvas interlining. It is extremely stiff, extremely light and gives a lovely crisp finish. Some people use it for corsetry in multiple layers instead of coutil and it is also used extensively by tailors and dressmakers for interlining bodices. In dressmaking, this fabric makes an excellent dress foundation and it is also used as a stiff petticoat matirial in vintage dresses.
The fabric is not pre-shrunk, I would not recommend washing it as the stiffening agents in the fabric will be washed out, however steam shrinking before cutting is advisable. Colour is 'natural' though it is a very pale, almost white 'natural'.
