If you mean: “I want to sew a cheap test version before cutting the real fabric”
Toile / muslin
Also heard as test garment · mock-up · fit muslin
A trial garment made to evaluate shape, proportion, construction, and fit before committing final material or production resources.
- Why it matters
- It makes pattern changes visible and inexpensive, especially when the test material behaves reasonably like the intended fabric.
- Say or ask
- “Should this toile test only shape, or must its weight, stretch, and drape represent the final material?”
- Boundary
- Muslin is both a fabric name and a regional name for a test garment. A poor material match can create misleading fit conclusions.
