Basic Seams and Seam Finishes
Plain Seam The most common type of seam. Made with one line of stitching, usually with right side of fabric to right side. Standard seam 5/8 inch
Seam Finishes Treating a seam edge to prevent raveling. Make the seam stronger and longer wearing.
Type of seam finish Depends on the weight of your fabric and how much it will ravel. Firmly woven fabrics do not need seam finishes. Loosely-woven and sheer fabrics do require seam finishes.
Pinked Seam Finish Used on fabrics that will not ravel. Gives a neat appearance.
Pinked and Stitched Used on fabrics that will ravel slightly.
Zigzag finish Used on fabrics that ravel. May be done either close to the seam edge or over the edge of a seam.
