Colourless plastic solution that reinforces and locks fabric threads at raw edges, buttonholes and cut appliqués to prevent fraying. Dries clear on most fabrics and adds discreet strength to high‑wear points without stiffening excessively. Ideal for ribbon ends, seam allowances, patches and trims, and for stopping runs before they spread. Apply sparingly along the edge and allow to dry fully before handling or laundering.
