OK, notice the fairly open zig -zag stitch which has been done tosecure the 2 layers of this peek-a-boo embroidery together. Another name for this is REVERSE APPLIQUE. The Janome applique foot AP was used as this makes the task of sticthing around the heart much easier. Finally a second round of stitching with a satin sticth was done. Of course, this sticthing could also have been done in the embroidery hoop as an applique-in-the-hoop.
