French seams are wonderful for professional-looking, clean seams. The raw edge of fabric is essentially encased within the seam. They are perfect for light, delicate fabrics such as silk. This tutorial will produce a 5/8″ seam.
If you are making this silk scarf, you can use a french seam to join the two pieces of fabric end to end. While the seam will be visible, it will look very neat.
Pin the seam, with the wrong sides together.
Machine stitch, using only a 1/4″ seam.
Press the seam flat, then trim close to the seam.
Now press the seam downward.
Turn the fabric, so the right sides are now together. To help turn the seam, it can be helpful to run the tip of a knitting needle along the inside of the seam. Press the seam.
Stitch again, this time using a 3/8″ seam allowance. this will encase the raw edge.
Press the seam downward to finish the seam.
To finish the scarf, create a hand rolled hem along the four sides.
