As you can see from the video, fabric paint is just two parts acrylic paint plus one part textile medium. You can find textile medium usually in a white bottle by the acrylic paints. Textile medium enhances the way acrylic paint works with fabric. It controls bleeding of colors, reduces stiffness when dry, prevents uneven application and helps the paint adhere to fabric.
Once I made the paint, I placed a stencil I had designed and cut with my Silhouette Cameo on the shirt. I used a sponge brush so as not to pull the fabric, but if you come up with a better technique, please let me know.
After the paint dried, I removed the stencil and put the shirt on an ironing board. I then covered the shirt with a cloth and ironed each part of the design for 20 seconds.
The textile medium has instructions to keep dry (or unwashed) for 7 days. I assume that’s to let the paint really set with the fabric.
I’m a Wolf Den Leader in Cub Scouts. Making these shirts to give to our boys was a real treat. Because the Fleur-de-lis in the design, they can now use the shirts in place of their uniforms if they so desire .
