The interesting thing about the blending sticks is they don't show up on white fabric, well duh it's transparent. But when I added the ink to the fabrics the iridescent blender markings really popped onto the fabric surface. I will be working with this a bit more once I get the fabric heat set and washed. You can see the markings on the top of the fabric, in the pic where you see the whole fabric, it sorta glows.
