I’m taking a new leather handbag from idea to factory line and I need a product-development partner who can stay with me through every stage. The focus is a premium yet accessible leather design that reflects my brand’s modern-classic positioning and meets strict cost and quality targets. Starting with trend-aware concept sketches, you’ll refine the silhouette and construction details around three must-have features: generous inner compartments, a secure zipper closure, and a fully adjustable strap. From there, I’ll rely on you to build a production-ready tech pack, source leather and hardware options that deliver durability without blowing the margin, and liaise with sample makers until we land on a sign-off prototype. Key deliverables: • Initial mood boards and multiple concept sketches • Detailed tech pack with measurements, materials, BOM and stitching specs • Material and hardware sourcing recommendations (leather grades, zippers, fittings) • Prototype guidance and fit notes for factory sampling • Final production files ready for manufacturing hand-off Please highlight any CAD, Illustrator, or Clo3D skills, along with experience supervising leather goods through to mass production. My timeline is tight, so efficient communication and clear checkpoint files are essential. Looking forward to collaborating on a handbag that’s ready to win its place on the shelves.
