French seams encase the raw seam edges securely inside two seams. They’re necessary for delicate fabrics, because two seams are stronger than one and the two lines of stitching prevent fraying. But French seams also are fabulous for garments with simple, straight lines because they’re beautifully clean and neat, and need no more finishing. I’m hooked, mostly because I hate finishing edges.

Minna's center back seam is a perfect example.

    i’m having serious puckering with french seams at curves—like armholes and necklines….

    anyone have tips?

    (the fabric is a super thin cotton—possibly called voile, though i’m not sure—and a lightweight cotton lining)

    is it a lost cause?

      I have been taught that while french seams are perfect for sher fabrics they just don’t work for curves at all-the bulk of the extra fabric inside the seam creates that ugly rippling effect!

    Hi Mynrose, I think what fitzfabulous was trying to say is divide the seam allowance as evenly as possible as halving 5/8" and sewing 5/16" is a bit tricky! Its also easier to sew a narrower seam first, then finish the french seam with a wider seam so there’s less change of the first raw edge poking out to the ‘good’ side of your garment.

    Ghainskom, you would press your finished seam to one side.

    This method sounds interesting but does it means that you don’t press seam allowances appart (since they’re encased in the seam)?

    hi, can someone help me, step number one is confusing me with the numbers.

    “Take the seam allowance of the seam and divide it into two whole numbers. So a 5/8″ allowance becomes 2/8″ (1/4″), plus 3/8″.”

    what do you mean dividing it into two whole numbers?

    Cool! I was looking for ways to finish seams and sounded interesting, but isn’t there a lot of bulk at the seam when you do this??
