The whip stitch is a simple sewing technique used to join two pieces of fabric together. It involves passing the needle and thread through the edge of one fabric layer and then catching a small amount of the second layer, creating a series of small, diagonal stitches. This method is often used for hemming or closing seams, providing a neat finish. This stitch is commonly employed in various sewing projects, including quilting and garment construction. It is particularly useful for securing linings or finishing edges without visible stitches on the front side, making it a favorite among both beginners and experienced sewers.
