MATERIALS YOU WILL NEED FOR THIS COURSE
To get the most out of the training and achieve high-quality sketching results, you’ll need the following materials. I’ve also included sample links from Amazon for your convenience.
1. Markers and Paper
- Alcohol-based markers such as Copic, Molotow, Winsor & Newton Promarker, Zig, Chartpak, Stylefile, or TOUCH (any professional marker brand will work). More on it below.
- Marker paper, size A4 or Letter (at least 70g/m2): This lightweight paper helps preserve your markers’ pigment and makes blending easier. Example: Canson marker PAD
Tip: Regular paper will also work for practice.
2. Grey Markers
- At least three shades of gray:
- Light (e.g. N2 / C2). Example: Warm Grey #2 (Chartpak)
- Medium (e.g. N4 / C4)
- Dark (e.g. N6 / C6)
Examples:
Here is a nice Copic grey set of 5 + liner: Copic Sketch Alcohol Marker 5 Colors + Multiliner SP Set, Sketching Grays
Set of 6 from W&N: Winsor & Newton ProMarker Set, 6 Count, Neutral Tones
3. Coloured Markers
- At minimum, please prepare these 5 essential colours:
- Beige, Sand, or Light Brown. Example: Potato Brown (TOUCH)
- Dark Brown or Chocolate
- Olive
- Deep Red
- Deep Blue
Example: Here is a nice set I like: Copic Marker 12 Piece Set - Architecture Colours
4. Highlighting Tools
- White pastel pencil (e.g. Caran'd’Ache)
- White ink gel pen (e.g. Gelly Roll, Sakura)
5. Linework Tools
- Black liner or waterproof fineliner (e.g. Copic Multiliner, Uni Liner, Faber-Castell)
- Pencil (I use Palomino Blackwing), eraser, and ruler
- Optional: Architect’s ruler (ideal for precise measurements and drawing to scale). Example: Architect's Scale Ruler (Inches)
