A water based acrylic medium used to convert Jo Sonja's Artists' Colours into fabric paints, which become permanent when dried and heat set. This finish can be washed and dry cleaned and should be applied to natural, non-synthetic fibres. Textile Medium is only necessary if the fabric is to be laundered or dry cleaned. Pre wash all fabric, prior to painting to remove sizing from fabric fibres. A MINIMUM of 50% cotton fibre content is recommended for best adhesion.
