@faimyxstitch: Do you need a fabric medium? If you want to paint on fabric using colors that weren’t made for fabric specifically - the answer is yes. Mix a little bit of fabric medium (I use acrylic medium by Liquitex), and the colors will become permanent. You can wash the cloth and enjoy the painted surface. Before using it, I recommend trying it out on a small piece of the same fabric you’re planning to use. Wait for it to try and check if the color stays in. The final tip: I find unbleached fabric to be the best for painting. I can see more color than on white cotton, for example #paintingonfabric #fabricpainting #handembroidery
