Watercolor crayons are one of the most amazing creative tools available. Not only do these crayons offer a bounty of options, but I feel much more comfortable working with them than with watercolor paints and a brush. While the crayons are applicable to an array of techniques, I have chosen to demonstrate what I consider to be one of the best ways to use this tool.
A simple black colored pencil is great when adding personal markings to your work. Generally these would be added at the end of creating a piece; however, this is not a hard and fast rule and should be done when you feel it needs to be.
With a damp fingertip or damp cloth, begin to rub the color, as this will erase any deep lines that may appear within the shading.
A second option is to draw straight lines from the edge down into your work.
Again, with a damp fingertip or damp cloth, smear the lines to create broken pieces of shading.
