These finishes totally enclose the cut edge of seam allowances and prevent raveling. They also enhance the appearance of the inside of the garment. Bound seam finishes are a good choice for unlined jackets, especially those made of heavy fabrics or those which ravel easily.
The most commonly used bound finishes are the bias bound, tricot bound and Hong Kong finishes. Medium-weight fabrics such as chino, denim, linen, gabardine, and flannel, and heavyweight fabrics such as wools, velvet, velveteen, and corduroy can utilize any of the three. Begin each of these finishes by sewing a plain seam. Bound finishes can also be used on hem or facing edges.
Bias bound is the easiest bound finish. Use purchased double-fold bias tape, available in cotton, rayon or polyester, to match the fashion fabric.
Tricot bound is an inconspicuous finish for most fabrics. Precut sheer nylon strips are available in 5/8" (1.5 cm) or ΒΌ" (3.2 cm) width. Use the narrower width for binding seams.
Hong Kong finish is a couture technique used on designer clothing, but because it is so easy and gives such a fine finish to the inside of a garment, it has become a favorite of many home sewers.
