You can definitely mix the quartz waste with epoxy. In fact, it can be mostly waste, with just enough epoxy to bind it together.

What you're supposed to see in those pictures is how the fabric drapes. From a flat piece of fabric you can only see the weave (if zoomed in), the pattern and the color.
