Experimenting with painting on fabric

I have experimented using Van Gogh‘S paintings as an inspiration for the experimental pieces. These are watercolour on cotton. On some I have also used biro used on them. I like the washed effect of the colour but the colour fades as the fabric dries. Earlier in FAD I experiment in the same way with acrylics. They do not wash out and by watering them down the same effect can be achieved.
