How do I sew a blind hem using the Blind Hem Foot?

Snap on the Blind Hem Foot and set the machine for a Blind Hem Stitch or Stretch Blind Hem Stitch. Finish the edge of the hem, fold and press it, then turn back to create a fold about ¼" from the top edge. Position the hem under the foot so the fold is against the center guide, and turn the knob on the right side of the foot to adjust until the widest zigzag stitch catches only 1 or 2 threads of the fabric fold.
