Durable spring‑loaded clips that hold fabrics securely without distortion—a smarter alternative to pins when working with thick quilts, heavy fabrics, vinyl or pile. Ideal for binding, bagmaking and serging prep, the semi‑transparent bodies keep your seam line visible and are quick to reposition or remove at the machine. Large size delivers extra opening and grip for layered projects, while flat bases glide under a presser foot for smooth feeding.
