A new pin for quilters and sewists that can be opened and closed with one hand! Wonder Pins are strong enough to pierce multiple layers but thin enough to go through fabric without leaving holes. They are so easy to pin through fabric and always easy to see. Wonder Pins are great when a sturdier thinner pin is necessary to pierce thick layers without bending. A much better way to pin baste quilts. The smooth locking feature of the Wonder Pin ensures that it is held securely in place on a broad range of fabric types from the very fine to the very heavy.
