Press your bias tape in half with wrong sides together. Pin the folded binding to your neck opening, aligning raw edges. Again, use a slight amount of tension to help the bias lay flat. The key is slight – just enough that the bias hugs the seam without pulling or becoming too narrow.
Bias facing describes the technique used to sew bias binding tape as a facing rather than a binding. So the bias tape is instead turned under the main garment edge and stitched into place to finish the fabric edge off. Bias facing is usually hidden, while bias binding is visible.
French binding is a versatile bias binding technique that is used to enclose the raw edges of light weight and sheer fabrics. The finish is quite beautiful around necklines and armholes when neatly and meticulously done in either matching or contrast colours or fabrics.
Open out the binding and lay it along the edge of the neckline or armhole to work out where the two ends will ‘butt up’ against each other. Use your fingers or nail to press a crease at the point. Use that crease as a stitch guide to stitch the two ends together.
