Greige goods vs. custom mill run
Start with what is already available
Greige fabric is unfinished material that may still need dyeing or finishing. It can be a useful base if the construction and weight fit, but the finishing step, color lot, testing and yield still influence quantity and timing. An existing finished stock fabric can reduce setup, though shade, composition, weight and available yardage may constrain the design.
A custom mill run can offer more control over construction or color but introduces material development, minimums and approval dependencies. Confirm any reservation and repeat availability rather than assuming the same lot will remain accessible.
