Using a Felling Foot
Added Sep 27, 2012
Place the two fabric pieces together so that the lower layer sticks out 1/4 inch past the top layer. Again, if you have a wider foot, your lower layer will have to stick out a little farther.
If you want one row of stitching to show on the outside of the garment, start with right sides together. If you want two lines of stitching to show, start with the wrong sides together.
