Choosing the right knitting structure for a development sample is essential because it determines how the final product will look, feel, and perform. The structure should match the design intent and functional requirements—such as stretch, thickness, breathability, and durability. For example, rib structures offer elasticity, while jersey provides a smooth surface. It’s important to test how the structure behaves with the selected yarn, including its stability, recovery, and drape. Selecting the correct structure in the sample stage ensures accurate evaluation of fit, appearance, and production feasibility.
