Seam edges support the garment and should be givxm a durable finish where fabrics have a tendency
to fray.
The zigzag slitch BL is ideal for such finishing. Place the stitching near the edge of the scam allowance,
and then trim away excess fabric.
For an overedged seam, the blind stitch BO makes a durable bulklcss finish. Good for straight grain,
lengthwise scams.
Seam edges should be trimmed evenly, and the stitch then iormed over the raw edge.
