Jo Sonja Textile Medium is an additive used to make painted designs on natural and non-synthetic fabric permanent when the fabric is laundered or dry cleaned. It is intended for use with Jo Sonja Artists’ Colours and fabric containing at least 50% cotton for the best adhesion.
Mixed with colour before painting, it helps the paint penetrate the fibres and will remain stable after it has been heat-set. It should be used on pre-washed fabric, allowed to dry for at least 24 hours, and then heat-set with an iron, making it suitable for fabric painting where durability through washing is required.
