HEIRLOOM fusible bias tape is pre-folded iron-on tape for stained-glass quilting, appliqué lines, and decorative outlines on fabric projects. The roll measures 6 mm (1/4 in) wide by 5 m (500 cm) long in Black, designed to be pressed in place for clean curves and straight runs. After fusing, stitch along the edges for durability and use a bias tape maker when you want to coordinate the look with custom fabric strips.
