Needlework, for short, can be referred to as either TAT or TATS. TAT is an acronym for 'tapestry and textile, ' which is a form of needlework that involves the creation of decorative fabrics and wall hangings. TATS stands for 'tapestry and textile stitching, ' which is a more specific type of needlework that involves the use of a needle and thread to create intricate designs. Both terms are used to refer to the same type of craft.
