French Seam8:50 PM
French Seam: a type of seam finish that encases raw edges so the seam does not fray at all. This type of seam can only be used on lightweight fabrics, and straight (not curved) seams.
To make a French seam:
1. Sew seam at 3/8" with right sides together and trim seam allowance to 1/4".
2. Press seam open.
4. Fold and press seam back on itself with right sides together.
5. Sew pressed seam at 1/4".
6. Press seam to one side (towards back if applicable). Now you have a completely finished seam allowance. No fray here!
Note: Only use the French seam finish on straight seams (not curved) like side seams or CB seams. The heaviest weight fabric to use French seams is quilting cotton. French seams are perfect for chiffon skirts.
