I had an idea of putting paintings on to fabric.
Began with fabric paints a long time ago and the French Art Shop used to sell fabric paints. One day they stopped selling them and told me to use acrylic paint and add fixative to the acrylic paints, Then wait for it to dry.
Then put a clean T towel and iron it to set the colours in. Then I just wash the clothing as normal and have no trouble with it.
