Wonder Pins are a revolutionary pin concept leveraging the benefits of both straight pins and straight pins in a single pinning tool! They are strong enough to pierce multiple layers but then enough to go through fabric without leaving holes. Easy to use and easy to see! Wonder Pins are great when a sturdier, thinner pin is necessary to pierce thick layers without bending and provide a better way to pin baste quilts! Use for sashiko piecing, boro and more! Simple to use - open and close with one hand! Each pin is 1 1/4" long with 20 pins per package.
