Tutorial 1: Design Sketching Process of the "Kumm" Coffee Maker
“Kumm” the concept Turkish Coffee Maker, is one of my self-initiated design projects. With this concept, my aim was to take an old cooking technique make it suitable for home use. I use a Copic A3 marker pad and a ball point pen for the product drawing before starting the marker rendering process.
For the matte and dark products, I start with the light colors like N2 and N3, or C2 and C3. This way it’s easier to control the whole process. Layer by layer, darker colors such as N5 and N7 can be used. Keeping in mind that the light is coming from the left side, I mainly focus on the right side of the product, because it has to be darker. It’s very important to use the marker in the direction of the surfaces.
After creating nice layers with various grey tones, it’s time to use Copic 100 or 110 for black effect.
Designers think while they sketch, and sketch what they think. Time is often a factor for busy designers, so unless we're doing a detailed illustration, we have to express the ideas quickly. I always try to focus on the whole product; other materials, color combinations, reflections, etc. These are very important for the sketching process. Here I grab the YR21 to create the first layer of the copper/brass material.
To get the reflective copper/brass effect, I support the light colors with darker ones like E57, E59, and N5. Also, for the matte black effect I don't leave any white on the body.
During marker rendering, sometimes I pass over the existing lines with the ball point pen to make them stronger.
