If you try this without a walking foot ... and have taped the three layers to a table as you layered them to be sure all wrinkles are out and have pinned closely (maybe every three inches) and adjusted the tension on the presser foot ... "pin" the fabric together with your stiletto one inch in front of the needle as though walking the stiletto down the stitch line as you sew. This should help to keep the fabric from creeping. You should have a sharp stiletto which will go down to the bottom layer. Just a suggestion...
