1. Cut two strips of fabric the length of your garment seam that you are adding on to, and the width of your choice. I cut mine 33 inches long as that was the length of jacket that needed buttons, and 5 inches wide. The finished product had just over an inch of expansion on each side.
2. Lay your strip down on the edge that you will be attaching it to, right sides together. Pin and sew a 3/4 inch seam.
|I am pointing to where the edge lies on top of the stitched line|
|This fold seam here on the right, the side with the pin closest to it,|
is where the stitch line and edge lie underneath.
|The seam on the right is where the coat front used to end,|
what I am holding is the extra length.
