The mock French seam is another easy way to create a clean finish on your seams for light to medium weight fabrics. It encases the raw edge in the same way that a French seam does, but the sewing technique is slightly different. The ‘mock’ french seam finish can be used on curves, unlike the traditional French seam.
Step 1: Pin the RIGHT sides of your fabric together.
Step 2: Stitch together using the seam allowance specified on the pattern.
STEP 3: Press open the seam allowance.
STEP 4: Press one side of the seam allowance in half so that the raw edge meets the center of the seam.
STEP 5: Press the other side of the seam allowance in half so the raw edge meets the center of the seam.
STEP 6: Bring both of the folded edges together and press.
STEP 7: Edge stitch 1/8″ of from the folded edge.
STEP 8: The raw edges are encased inside the folded seams for a neat finish.
This is how the finished seam will look below.
