Lawns and voiles are a little bit lighter weight than regular quilting weight cotton, and can sometimes be a bit sheer. Lawns are usually 100% cotton, but voiles can be rayon, cotton, or others, so be sure to pay attention to the content if that is important for your project. (Currently, all of our lawns and voiles are 100% cotton.) Both lawns and voiles are great for apparel, from blouses to skirts. They also wash up super soft and can be a nice fabric for a quilt.
