Fabric folds are a type of decorative technique used to add texture and shape to garments. HEMS, which are four letters long, are the most basic type of fabric fold and involve folding the edge of the fabric over itself and stitching it in place. PLEATS, which are six letters long, are more complex and involve folding the fabric in an accordion-like fashion and stitching it in place. Tucks, which are five letters long, are similar to PLEATS but involve folding the fabric in a zigzag pattern and stitching it in place.
