A French seam fully encases any raw edges and is fantastic for fabric that has high fray rate. It is best used for straight or slightly curved seams. Any seams with too much of a curve will be a nightmare to sew and also not lay flat against the garment.
Please take note that a total of 1/2" seam allowance has been allocated for this pattern.
Pressing from the right side will allow the iron to naturally open your seam flat. Check out my Pressing Tips here.
