Here our experts show you how to do French seams. Yes, it’s a little trickier than doing a plain seam but no need to worry, the French seam is just a series of plain seams and folds. Ideal for use on delicate or sheer fabrics, this is the perfect seam to strengthen joins and make your sewing projects more robust!
How to do French seams
Begin by pinning the wrong sides of your fabric together along the raw edge. Machine straight stitch with a 5mm seam allowance. Trim the excess fabric near to the stitch and press seam open. For this seam it’s a good idea to set your sewing machine up near your ironing board and iron as it requires a lot of pressing!
Fold the fabric so that the right sides are together with the raw edges of the seam enclosed and pin in place. Machine straight stitch a 10mm seam allowance along the stitched edge, running parallel with the first line of stitching.
To avoid the delicate fabric puckering, adjust the straight stitch length according to the thickness of the fabric you’re working with. If the fabric is thinner use shorter stitches and if the fabric is thicker use longer stitches.
Turn the right side out and press so that the seam sits flat to one side. You should only use French seams when working on straight edges as they are too bulky to use on curves.
It really is as simple as that. We love using this seam to get a really neat and professional finish on handmade clothes, cushions and other sewing projects.
