How do I actually go from a rough idea to a working prototype?
The short answer
Don't design in a vacuum, sketch the concept, then get it into a factory's hands as a rough CAD file or even a hand-built mockup within your first few weeks, because feedback on a physical thing beats another week in Figma. Most Indian manufacturers will iterate off a reference sample (buy something similar off Amazon/IndiaMART and mark it up) faster than off a spec alone. Budget for 2-3 rounds before you have something worth showing a customer.
