How do I use the Sew Easy Foot on my Singer Simple sewing machine?

First, snap the Sew Easy Foot onto your machine and ensure the needle is in center position. Select your desired seam allowance (⅜", ½", ⅝", ¾", or 1") using the marked extension and movable fabric guide. Place the fabric under the presser foot with its edge along the guide and stitch your seam with the desired seam allowance. (Page 9)
