|Acrylics, crayons and pencil on stretched canvas, |
I've experimented a lot recently with pencils and crayons on different surfaces, largely to test whether or not they are waterproof (i.e. whether they bleed or not) under acrylic media.
The white colored pencils I tried all work well and are waterproof on very smooth substrates except for the Stabilo All, which is essentially a watercolor pencil although it's made to use on glass and other impervious surfaces. None of the white colored pencils work well on canvas textured surfaces.
All of the regular (graphite) pencils work well on virtually any surface, including the "black" Stabilo All. Charcoal pencils don't work at all -- meaning they bleed.
I've also tried several brands of pastel pencils, and all work well on smooth surfaces but not well on canvas textured surfaces. They all break/crush with pressure.
Caran d'Ache Neocolor I crayons are highly-pigmented wax crayons, kind of like Crayola Crayons on steroids. They work well on all surfaces (there are some Neocolor I orange lines in my painting above) and are waterproof. The Neocolor II crayons are watercolor crayons. They can be covered over with medium but will smear a bit. Of course with water, they disperse their pigment quite readily.
I have a set of Niji Oil Pastels that I love. Not only are the least expensive (set of 36 from Blick for under $7.00), but they're fairly creamy so I like them a lot for use on paintings. Oil pastels in general can be fixed with acrylic medium; chalk pastels cannot be. You must use spray fixative for the latter, which, like regular spray paint, I hate using. Caran d'Ache NeoPastels are also good, although they're more expensive and I personally don't like them as much as the Niji's. However, where the Niji color line is lacking, I've filled in my palette with the NeoPastels. I've also tried the Sakura Cray-Pas pastels but find they are too hard, so they require way too much pressure to get anywhere near the color load of the Niji's or the NeoPastels.
I'm reading, among everything else, Steal Like An Artist by Austin Kleon. Short, wonderful, quirky, inspiring.
