Any fabric can be used as a quilt fabric. Just be aware of the fact that some fabrics won’t sew as easily as cotton. Quilters usually use 100% cotton fabric in their quilts because this is one of the easiest fibers to sew; it’s washable and will ‘hold up’ over the years. Today quilters can buy fabric by the yard or purchase pre-cuts. In the photo, the fabrics on the left have been cut by the yard. The stack of 10 inch squares on the right is a pre-cut.
