What is fabric medium?

Fabric medium is a type of clear liquid additive that is mixed with acrylic paint when painting on fabric. It helps to improve the flow and adhesion of the paint to the fabric, as well as increasing the color's longevity and washability. Fabric medium also helps to prevent the paint from stiffening once it dries, allowing the fabric to remain soft and flexible. It is especially useful for painting on clothing, upholstery, and other fabric surfaces that will be washed or exposed to wear and tear. Fabric medium can be mixed with acrylic paint in various ratios, depending on the desired consistency and opacity of the paint. It is available in art supply stores and online.
