The first custom bag sample is a learning tool. It reveals proportion, capacity, access, carrying comfort, material behavior, and construction cost before production money is at risk.
Common stages include paper mock-up, structure sample, material sample, and pre-production sample. Not every project needs every stage, but understanding the sequence prevents wrong expectations.
Review size, access, carrying comfort, pocket placement, shape, and waterproof or protective requirements before focusing on logo, color, or finishing details.
Review the brief before sampling, choose the right sample stage, comment in writing with photos and numbered notes, and separate personal preference from functional failure.
