Intro to Graphic Design: Illustrating Badges and Icons with Geometric Shapes
Dominic Flask · Independent Designer and Illustrator
A working designer walks through his real sketch-to-vector process for icon badges, but leaves nearly everything to the student.
What it actually teaches
The course follows a three-part arc that mirrors a real design job: generate ideas, build the visual system, then finish the series. The first stretch is the strongest conceptual material, walking through a mind-map exercise (one word in the center, branches of loose associations, no filtering yet) followed by rough thumbnail sketching. The teacher works through two of his own concept paths, a mid-century interior-design idea and a series of Wichita landmark badges, showing why the first got abandoned (it sprawled into too many unrelated objects) and why the second held together (every badge could sit inside the same map-marker shape). That contrast is a genuinely useful lesson in editing ideas down, more useful than most "brainstorming" lectures that stop at the mind-map itself.
The middle section is where the course earns its "geometric shapes" billing. It opens with a taxonomy of shape types before settling on why squares, circles, and equilateral triangles carry the whole series. From there it moves into dense screen-recorded Illustrator work: aligning eyes to a body with the align palette, cutting corners with pathfinder minus-front, turning two overlapping squares into a compound path so a bounding box behaves correctly, and using the intersect filter to carve a shadow shape out of an arm. A recurring trick is drawing with strokes rather than filled shapes, seen in a bicycle frame built entirely from the line segment and rectangle tools, and in dashed strokes standing in for a fountain's water. The offset path function gets its own demonstration for building sticker-style outline effects. None of this is explained conceptually first; it is shown by doing, so the value depends entirely on being able to follow along inside Illustrator.
Where it holds up and where it thins out
The Gestalt principles lesson (similarity and anomaly, illustrated through a sun-ray badge and a Saturn-in-a-night-sky badge) is short but sharp, giving a vocabulary for why certain compositions read as unified rather than random. The color palette lesson is the most transferable single idea in the course: starting from a city logo's harsh primaries, muting them, then deliberately choosing pairs where one color can double as another's shadow. That structural thinking about color, not just aesthetic taste, is worth the price of entry on its own.
The finishing lecture covers inner shadows and highlights via duplicated, offset, and blended shapes at low opacity, texture built from a live-traced ink stipple brush, and pixel-snapping in Pixel Preview mode before exporting a crisp PNG. Useful, but delivered at a clip that assumes the viewer already has strong Illustrator fluency; someone unfamiliar with compound paths or the pathfinder panel will lose the thread quickly. The course also leans heavily on one instructor-made project as its running example, so a student's actual learning depends on classroom peer feedback that no longer exists outside the original live cohort. As a screen-record of an experienced illustrator's habitual workflow, it delivers real technique; as a structured beginner curriculum, it asks for prior skill the "beginner level" label does not admit to.
The standout
Building a five-color palette where each color also functions as another color's shadow, so shading becomes a lookup rather than a guess.
What you will learn
- How to mind-map and sketch a concept before touching software
- The five categories of shape (geometric, organic, rectilinear, irregular, hand-drawn) and why geometric ones are used here
- Illustrator construction tricks: align palette, pathfinder unite/intersect/minus front, compound paths, offset path, and stroke-as-shape
- Gestalt principles (similarity, anomaly) applied to badge composition
- How to build a primary-plus-neutral color palette with built-in shadow and highlight relationships
- Simple shading and texture techniques using transparency modes (screen and multiply) and pixel-snapping before export
Best for: Illustrator users who already know the basic tools and want a working method for turning simple shapes into a cohesive badge series.
Skip it if: Complete software beginners, since the class assumes comfort with the pen tool, pathfinder, and keyboard shortcuts from the first drawing lesson.
