Iron-on twill patches in Primary colours for quick repairs and decorative appliqué. The heat-activated backing fuses to most medium-weight fabrics, creating clean mends at knees, elbows and high-wear areas. Made from 35% cotton / 65% polyester twill, they balance durability with flexibility. Package contains 4 pcs; follow ironing directions and launder after adhesive has fully set. Suitable for most medium to heavy-weight wovens; avoid delicate fabrics.
