To stretch a strip, steam-press it firmly while stretching it with the other hand. Depending on the fabric and degree of stretch, the strip may become narrower in the process. Swirling means shaping a bias strip to go around a curve, and should be done with both hand-cut and packaged strips. Steam-press firmly, stretching one edge and easing the other, as shown. Always start the application of the strip at an inconspicuous spot.
Seam ends together on the straight grain, close to fold of garment.
Finish stitching strip to garment, across the joining. A bias strip should be pinned in place before stitching, especially around curves. On a close curve, basting is definitely necessary. Its finished width varies. Pre-crease the strip for easy application.
