🟦 MATERIALS:
• Grid paper (essential)
• Pencil and ruler
• Black pen or marker (for outlines)
• Color pencils/markers (Yellow, Blue, Purple)
⸻
🧩 STEP-BY-STEP INSTRUCTIONS:
⸻
1. Understand the basic unit: a cube
Each cube has 3 visible faces:
• Top face: Yellow
• Left face: Blue
• Right face: Purple
You will repeat this unit to create the illusion.
⸻
2. Start with a triangle layout
The full design forms an equilateral triangle made up of cubes. It consists of 4 rows:
• Row 1: 1 cube
• Row 2: 2 cubes
• Row 3: 3 cubes
• Row 4: 4 cubes
→ forming a 10-cube triangular pattern with a hole in the center.
⸻
3. Drawing a cube on grid paper
Each cube is made using rhombuses (diamond shapes):
• Use 2 diagonal squares on the grid for width and height of each face.
• Draw 3 connected rhombuses (top, left, right), forming a cube.
👉 From the top-down view, it should look like a 3D cube pointing outward.
⸻
4. Draw the bottom row of cubes (4 cubes)
Start from the bottom-left:
• Draw a row of 4 connected cubes diagonally upward.
• Leave a space between each to match the final triangle shape.
⸻
5. Draw the 3-cube row above
Above the 4-cube base, center a row of 3 cubes.
Align them diagonally to form the triangular structure.
⸻
6. Add the 2-cube row
Above that, draw 2 cubes similarly aligned in the center.
⸻
7. Add the final top cube
Place 1 cube at the top, centered.
⸻
8. Leave the center empty
Leave the middle cube missing to create the triangle hole illusion in the center.
⸻
9. Outline all cube edges
Use a black pen or marker to trace all cube edges.
• This sharpens the 3D effect and defines the illusion.
⸻
10. Color each face
Stick to this color pattern:
• Top face: Yellow
• Left face: Blue
• Right face: Purple
Use strong shading to emphasize depth.
⸻
🎯 FINAL RESULT:
You now have a 3D cube triangle optical illusion that pops off the page using simple geometric units and color.

✅ Step-by-Step Drawing Instructions

Step 1: Draw the Central Circle
• Start with a medium-sized circle in the center of your page.
• This is the anchor for the rest of the pattern.
Step 2: Add the Inner Petal Shapes
• Inside the circle, draw symmetrical petal-like shapes radiating outward from the center (like a flower).
• These petals appear pointed and equally spaced.
Step 3: Outline the Petal Tips
• Around the edge of each petal, outline a second layer to give them thickness.
• The tips are sharp and defined.
Step 4: Add a Second Layer of Petals Outside
• Between the gaps of the first set of petals, draw a second layer of larger petals.
• These should also radiate out and align with the center.
Step 5: Draw Geometric Borders
• Surround the second petal layer with a border (circle or square frame).
• These are typically used to separate the floral design from outer patterns.
Step 6: Add Corner and Side Details
• In each corner of the square (if it’s framed), draw small geometric patterns or leaf shapes.
• These details are usually symmetrical and repeat in each corner.
Step 7: Fill in the Background Pattern
• Add small repeating shapes or line decorations to the spaces between the petals and the border.
• Keep them light if you’re planning to color the main flower.
