Longer, stronger curved safety pins sized for thicker quilts and layered sewing. The arc helps the point catch the clasp cleanly through battings and backings, making basting more comfortable and reducing fabric shift. Nickel‑plated steel resists corrosion and glides smoothly. A 60‑pack is perfect for larger quilts or as a top‑up to your basting kit. Always test on a scrap of your project fabric to confirm results and removability.
