Buttonhole Elastic
3/4" wide with buttonholes in elastic every 1" along center of width.
This is getting harder and harder to find. VERY wonderful product for wait shifts, and in children's clothing as used in ready-to-wear clothing. My little grandson needs it in all his pants - if they're to be long enough, yet stay up!
Makes any outfit adjustable in the waist with this clever buttonhole elastic. Simply insert the elastic into a casing, leave the ends sticking out, and place a buton near the openings for the elastic to loop around. This is ideal for keeping fast growing kids in the same size for a little longer, and it is our favorite notion for comfortable pants at holiday feasts!
