Clovers Wonder Pins are a revolutionary pin concept leveraging the benefits of both straight pins and safety pins into a single pinning tool. Wonder pins are stroing enough to pierce multiple layers but thin enough to go through fabric with out leaving holes. They are so easy to pin through fabric and always easy to see. They 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. Benefits: Pin fitting garments is so much easier, a much better way to pin baste quilts and perfect for boro and sashiko piercing. How to use: Step 1: Insert the point down through the fabric layers and push to expose the thin sharp point. Step 2: Push down on the closure to either lock in place or release for removal.
