Hey everyone, Darra here! Kassa chalk markers and chalkboard vinyl are two of my favorite tools for illustration! It is an entirely different experience from illustrating on paper because the black parts are already there and you have to add the white!
Adding the White
Since your “paper” is black, you have to work backwards! Instead of leaving the white parts white, and adding the black, you have to leave the black parts black and add the white! If you do this, it will make the drawing look a lot more realistic, because you need black for shadows. As your drawing, just remember this because it’s really easy to forget and draw the way you’re used to!
Sometimes there will be areas that aren’t fully black, but still darker than the regular color. Hatching is one way to shade these areas. Just make strokes that form parallel lines, a little ways apart from each other. The farther apart they are, the more black will remain, the darker that part will seem. If you need the area a little lighter, put them closer together.
To lighten the area, use cross hatching. Cross hatching is when you cross over your hatch marks going into the opposite direction. This will make little squares in the black parts that separate the lines! The area will be light than the hatched parts, but not as light as fully coloring in the area.
Make the Hatches Closer Together
If you add another line of cross hatches in the spots where the squares are, it will lighten the area even more without fully covering it. This step just adds a little depth and dimension to your work!
Blending With Water
If you don’t like the cross hatching look, you can blend with water! Take your Kassa water brush and rub over the areas mixing in a little bit of water. Since some areas have less pigment than others (hatched and cross hatched parts), they will remain darker! Make sure you leave the black spots black, to save your shadows
In the video below, you can watch me make an owl illustration using these techniques! If you try it out share it on Instagram with the hashtag #kassamoment so we can see your wonderful work!
