Basic Seams and Seam Finishes
Plain Seam The most common type of seam. Made with one line of stitching. Standard seam 5/8 inch.
What is a Seam Finish? A way of treating a seam edge to prevent raveling and to make the seam stronger and longer wearing.
Type of Seam Finish Depends on the weight of your fabric and how much it will ravel.
Which fabrics require a seam finish? 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.
