"Measure your mind's height by the shade it casts." Robert Browning
As you all probably know by now, I love my pastel pencils. I decided to do a little (very little) experiment to see how they would work for adding shading over my Tombow brush markers. First I tangled on an official Zentangle tile (3 1/2 inches square). I added color where I wanted it, using the markers. Now I could have shaded with the markers also, either by adding more layers of the same color, or using a darker color, but I have never had great luck with having those layers blend nicely into each other. So I tried my pastel pencils. Wherever you detect shading, that's the pencils. Unfortunately, as I blended them with my smudger (tortillon), the paper had some shredding and pilling going on. And I did not need to rub hard at all to do the blending. So I wasn't too happy with that, but I actually think it turned out pretty good, and you can't really notice the shredding. Since the Tombows are water based, I did wait a couple of hours before shading....maybe I should have waited even longer.
I decided to try another one, this time on watercolor paper to see if that would work any better. I cut a square, this one 4 inches, from 90 lb. Canson watercolor paper. I should have rounded the corners before taking my photo, but forgot...the squares I cut on my own always look classier with rounded corners. In the same manner as before, I colored my tangled design with Tombows, gave it a while to dry, and added the shading with the pencils. This time there was no pilling or shredding. Maybe I waited longer before shading? But I think it was because this paper is better meant to handle the watercolor.
Would I use my pastel pencils to shade over Tombows again? Definitely! But I will remember to do it on watercolor paper.
