How do you make a two tier quilt binding?

To make a two-tier quilt binding, first prepare your binding strips by cutting fabric into two widths—one for the inner tier and a wider one for the outer tier. Sew the inner tier binding to the quilt's edge, mitering corners as you go. Once the inner binding is in place, attach the outer tier by folding it over the inner binding, then pin or clip it in place. Finally, sew along the outer edge of the binding to secure it, ensuring a neat finish on both sides of the quilt.
