What is catch stitch?

Catch stitch, also known as a catch seam or blind stitch, is a hand-sewing technique used primarily in hemming or finishing edges. It involves taking small, discreet stitches on the fabric's surface while catching a few threads from the underlying layer, which keeps the stitches nearly invisible. This method provides a secure finish while allowing the fabric to maintain its drape and flexibility. It’s commonly used in tailored garments and delicate fabrics to ensure a neat appearance.
