Neutral grey iron‑on drill patches sized for knee and elbow repairs or personalized appliqué shapes. The durable twill surface accepts stitching and holds up to routine wear when fused with adequate heat and pressure. A great colour for workwear and casual basics, it blends into heather knits and grey wovens. Add to studio and classroom kits for fast, practical mending or design accents on bags, uniforms, and garments that see frequent abrasion and movement during use.
