Love to Sew Studio shows you how to sew a French Seam. The French Seam is a bulky, self-finished seam that is great for fabrics that fray. It is used on garments that are washed a lot like lingerie, and blouses. You will also find French Seam used on children's and babies clothing. The French Seam is found on babies clothes for two reasons. One, so that the seam allowance doesn't rub up against the baby's soft skin. And two, the French seams holds up well with clothes that are washed often. With a French seam the raw edges are completely enclosed in the seam. It should not be used on bulky fabrics or curved seams. Unlike, most seams made in garment making where the fabric is sewn pretty sides together, the French seam is made by sewing the fabrics wrong or ugly sides together.
