This stretch tape is perfect for preventing stretching in materials like knitting, knitwear, and jersey. It's made by processing fusible interfacing into a tape form and is used to prevent stretching. Softer than typical fusible tape, it's easy to apply along curves, and it seems to move with the fabric after application. I personally love using it for making doll clothes. Washable and dry cleanable. Ideal for doll clothes, knit sewing, and small crafts. ■ 12mm width ■ 20m roll ■ Material: 77% Acrylic, 23% Nylon
