No tools necessary, just loosen the wing nut, slide the Binding Folder into place and turn the wing nut to secure it in place. To create your binding, simply insert a 2.25 inch strip of fabric into the Binding Folder (note that there is a slot on top to allow you to use a pin to help pull the fabric through if necessary) then pull the binding and iron as you go. It's like having a 3rd hand to fold the binding in half while you iron. Size: 2-1/4in Strip Size. Color: Purple. CHK-3H225PRP
