Modifying a quilted surface

Misty Fuse, painted with Golden liquid acrylic paint, torn into rough-edged layers and fused to surface over paint.

I'm working on a small abstract landscape.  In trying to create a horizon with thread, I decided that some paint (eek!) and painted Misty Fuse might help create the line I am after.  I intend to quilt the surface more extensively where the paint and fusible have been applied, but decided to stop and photograph the progression of steps.  Prior to this, I admit to being hesitant about applying paint to a surface that has been extensively quilted (a little voice in my head saying, "What if you mess it up after all that work/time....then what?")  I am trying to shut the voice up and forge ahead.  What's the worst thing that can happen?
