Press the angle well then fold the strip back and press.
Sew the bias binding to the raw edges of the quilt with 1/4" seam allowance, starting about 2 inches in from the end of the binding strip.
When you almost reach the other end of the binding, stop sewing about 2 inches away from the other end.
Open the first end (the one with the 45 degree angle) and insert the second end into the first end of the strip. Trim the second end if it's too long, so that it fits inside the strip.
Smooth out the strip and align the edges as neat as possible.
Continue sewing the 1/4" seam.
Fold the bias binding up and press then fold to the other side of the quilt.
Clip with wonder clips and finish sewing the other side of the binding using the stitch in the ditch
