You wanted it - you've got it! Painting tutorial, illustrated by photos of making my Captain America inspired dress (aciddaisy.deviantart.com/art/C…
Advantages: very very very easy! Everyone are capable to do it, and result still will be very neat.
Disadvantages: you can't use it for the thin and light fabrics. Stretchy fabrics are in the risk zone too. Method is not good for small, complex and detailed pictures.
I used special acrylic paint for the fabric, russian mark "Decola", silver one from the standart set. It's not too runny and not too dense.
