2. Assembling the Flower Center

The center of the quilt is a small floral star.
Step by step:
1. Sew small diamonds together to form a circle
2. Join the pieces to form the central star
3. Iron carefully
Tip:
Always sew in pairs before joining everything.

3. First Layer of Petals

Now the larger petals begin.
How to make:
1. Sew two elongated pieces together to form a point.
2. Make several identical units.
3. Position them around the center. Ideally, assemble everything on a surface before sewing them together permanently.

4. Second Layer of Petals

This is where the mandala effect is created.
• Alternate:
• Dark purple
• Light lilac
• Floral
This creates depth and visual movement.

5. Joining the Circular Blocks

• Then assemble quadrants.
• Finally, join everything together. This prevents distortions.
