Buttonhole elastic is relatively new. It is an elastic product that has buttonholes woven into the elastic. The buttonholes allow you to adjust the fit of the elastic but do require an opening in an elastic casing for accessibility to the elastic and a button outside the casing to hold the elastic. The fitting adjustment that buttonhole elastic allows is excellent for children's clothing and maternity clothing. The end of the elastic needs to be turned under and stitched, serged or zigzagged to prevent the elastic from unraveling.
