Half-bias fusible stay tape is mainly used for curved sections. The materials available are polyester and nylon. You can choose half-bias tape and stay tape, focusing on Tohkai Thermo and Nittobo Advantex products.
For curved sections, half-bias tape is suitable because it is easier to follow the shape while limiting stretch more than bias tape. If you want to prevent woven yarns from shifting due to stress on the seam and creating gaps, choose stay tape for use in seam allowances and similar areas. Customer reviews mention that it is thin and does not create noticeable bulk, has a soft feel, and is less likely to detract from the texture of the fabric.
