Using Liquid Pencil for Grissaille Underpainting for Watercolor

The Derivan liquid pencil that I posted a review on last week comes with re-wettable and permanent formulas. I decided to use the Sepia toned, permanent liquid for an under painting for a daily drawing challenge sketch.

I did a basic outline with a 3b pencil and started playing around with the quantity of water and liquid pencil mix.

I decided on going as dark as I could at first to see if any of the liquid pencil would lift off with any subsequent 'washes'. It did pretty good-I did notice some lightening which I found to be beneficial. It dried quickly on my sketchbook paper so I was restricted to small areas where I wanted a softer edge.

I think my favorite aspect of this product is getting very fine lines with a mapping pen. I want to use this stuff on my next graphite drawing and see how it plays out with traditional graphite work.

It's nice being able to use something other than ink or pencil as grissaille for watercolors. The softness of the sepia tone added to this particular subject. I find that sometimes ink and pencil have a tendency to dirty the colors. I love the magic of grissaille and being able to relax and just focus on the shapes and light.

I bought mine from Jerry's Artarama and it is also available on Amazon.
