I sew the binding strip (2.5 inches) onto the back of the quilt using a 3/8 " seam. I mark the bottom corner and stop stitching at 3/8 inch. I take a couple of back stitches and lock the stitch.
Fold the binding to make the corner turn and again sew with a 3/8 " seam.
Fold Binding to the front and stitch down.
