Abstract: An improved tape for use in locating buttons and the corresponding buttonholes is formed of a perforated strip of fabric, paper, or plastic material with two corresponding series of locating indicia. The tape has a pressure-sensitive adhesive to adhere the strip temporarily to the fabric of a garment, and is perforated between the two sets of locating indicia.In use, two panels of fabric to have attached buttons and to be worked for buttonholes are laid side by side, or in overlapping relationship and the tape is adhered to both panels.The two halves of the tape are separated along the perforations, and the button and buttonhole indicia remain adhered to the panels of fabric, in perfect alignment until the sewing and working is completed.
