• Delivery time: Specific timeline?

Material consultation based on 15 years of experience in the industry:

• Genuine leather → High-end bags, long-lasting
• Simili → Affordable price, diverse colors
• Canvas fabric → Eco-friendly, youthful
• Waterproof fabric → Water-resistant, suitable for travel

Step 2: Design and Create Paper Samples

Professional CAD software like Lectra or Gerber is used to create accurate 3D designs. Hop Phat’s design engineers can adjust designs according to specific requirements within 2-3 hours.

Pattern makers are created with high precision, including:

• Main fabric pieces (bag body, flap, bottom)
• Accompanying accessories (straps, side pockets)
• Cutting and sewing lines in detail
• Step-by-step assembly instructions

Step 3: Material Selection
