A method and system for garment manufacture fixes a curable polymer in either a continuous bead or in a non-continuous or segmented bead onto a cut fabric piece. The cut fabric piece, the continuous bead and the non-continuous, segmented bead have a wide array of configurations. If the cut fabric piece has a contoured edge region, a silicone bead proximate that edge has a conforming configuration. In the method, the cut fabric piece is placed in a coordinate space. The location of the cut fabric piece is sensed and that information is used to control the movement of a curable polymer dispenser. The dispenser applies a curable polymer from the curable polymer dispenser onto the cut fabric piece in the desired configuration after which the polymer is cured. If the fabric is cotton, the curable polymer is drawn into the cotton fibers prior to cure. The flow of curable polymer from the dispensing head can be started and stopped as the dispensing head moves relative to the fabric, allowing the curable polymer to be deposited on the fabric in any configuration.
