## Form & Structure: The Foundation of Design
* Design is intentional planning for function, feeling, and communication.
* In tattooing, design determines flow and long-term longevity on the skin.

## The Primacy of Form
* Form refers to overall shape and mass, while structure is the arrangement and balance.
* **The Black Silhouette Test:** A design must work as a solid black shape first; the human eye processes silhouettes before details.

## Hierarchy of Perception
* Step 1: Silhouette (Cognitive Impact: 100)
* Step 2: Large Shapes (Cognitive Impact: 75)
* Step 3: Medium Shapes (Cognitive Impact: 45)
* Step 4: Small Details (Cognitive Impact: 15)

## Universal Applications
* **Tattooing:** Must flow with anatomical muscle structure.
* **Architecture:** Based on load-bearing frameworks.
* **Painting:** Value arrangement and under-drawing.
* **UI/UX:** Navigation hierarchy and layout grids.

## The 60-30-10 Rule in Design
* 60% should be dedicated to Primary Form.
* 30% to Secondary Forms.
* 10% to Details (where beginners often waste 80% of their effort).

## Critical Considerations for Tattooing
* Skin is a living filter; ink spreads and moves over decades.
* Weak structures fail as micro-details blur over time.

## The Core Laws of Design
* No shading or detailing until the structure and silhouette are established.
* Daily habit: Start every design with simple shapes and flat values.
