Chances are that the fabric is not suitable for regular quilting. It might be good for crazy quilt type designs. Then it depens on how comfortable you are working with different textures, fibers of fabric. I would imagine it is the same as for his costume design work. Guess it depends on what you might plan on making with it. Surely the owner could give you some idea of what type - decorator weight, silk, cotton, dress weight.....etc.
