Magic Pins Flathead Patchwork Extra Long Fine 0.5 mm Magic Pins Flathead Patchwork Extra Long Fine Pins are best for piecing delicate fabrics, handling multi-layered projects, and ironing. Their thin profile and heat-resistant, easy-to-grip handles make them an ideal sewing and quilting tool to prevent fabric puckering and hand fatigue. Why These Pins Stand Out Iron Over Them: The heads are made of heat-resistant silicone. You can press your seams flat right over the pins without worrying about melted plastic. Ergonomic Grip: The flat, ridged handles are easy to grab, making them a fantastic choice if you have stiff fingers or arthritis. No Snagging: The extra-long, ultra-fine shafts (0.5mm) glide through thin or delicate materials without leaving large holes or causing fabric pulls. Best Uses Quilt Piecing: The extra-long shaft easily holds multiple layers of fabrics and thick quilt "sandwiches" together securely. Delicate Materials: Because the pin is so thin, it is perfect for fine fabrics like silk, satin, or fine cottons. Machine Sewing: The flat head allows your sewing machine's presser foot to glide smoothly over the pinned fabric without bumping into bulky, round pinheads.
