These small-sized Wonder Clips are curved on the top and flat on the bottom with a narrower point, perfect for holding together small sections or tight corners. They work better on bindings than regular clips. Clips open wide to hold layers of fabrics-they aren't just for bindings; you can also use Wonder Clips instead of pins for vinyls and thick fabrics, and even English Paper-Piecing projects. Comes with an organized acrylic case 3" x 5" x 1-1/4". 1" x 1/4" x 3/8" at point.
