French seam

Schematic structure of a French seam: 1. Sew left to left (red stitch) 2. Sew right to right (green stitch)

With a French seam or right-left seam , the two pieces of fabric are first laid left to left - i.e. inside to inside - along the edge of the fabric and sewn from the right. The excess seam is cut off close to the seam. In the second step, the part is turned inside out and placed right on right - outside on outside. The first seam is now inside the part. A second seam is then placed so close to the first seam that the tucked-in seam part is completely enclosed. This creates a seam that does not have to be overcast and has no open fabric edges. In contrast to the lap seam , the French seam is not flat, but rather bulges inwards and is therefore preferred for thin fabrics. Since the seam is not sewn through from the outside to the inside like a lap seam, it is also suitable for sewing long tubular parts such as sleeves or trouser legs with a sewing machine that is not specialized for this purpose.
