Batik are created using a type of resist printing process in which wax is applied to the fabric in specific areas. When the wax hardens, the fabric is submerged in dye. The fabric is then boiled to remove the wax. This fabric-dyeing method makes cotton look crackled. Batik fabric can typically be found in dresses and household décor.
Many batik fabrics recommend hand washing and laying flat to dry. It's always good to test the fabric for dye fastness and use color catchers when you wash your quilts to catch excess dye. Because batiks have a tighter thread weave, they fray less and are a great choice for applique.
