This is an amazing tutorial. I never knew you could use rock salt on water colour.

lol I am actually wondering if you could explain how to use the copic blender. I have Pentone markers (couldn't afford copic) and I bought a blender. But I can't seem to make is blend smoothly. The blender ink itself always leaves a definite edge on the colours I am trying to blend. I am wondering if there is a special technique to using the blender marker.
