A great idea for the all-round artist. A way in which, if you feel like painting on fabric and making it last, you need not buy a whole range of fabric paints. MM13 Fabric Fixative mixed with Matisse Colours, preferably Flow Formula, will become permanent on T-shirts or most other garments after heat fixing.
Mix equal parts of Fabric Fixative and Matisse Flow Formula Acrylic, then paint and let dry before you heat-set with an iron to become wash-fast.
Heat-set by ironing on the reverse side of the painted area or put a tea towel over the painted area and heat-set with an iron. Do not allow the iron to make contact with the paint. For heat-set times, refer to the "painting on fabric" section in this booklet. Some synthetic fabrics are non-absorbent and thus not suited for paint application. It is possible to thin the paint with water and achieve stain effects or delicate watercolour brushouts. Test your fabric choice beforehand.
