Measuring 1¼ inch wide by 1¼ yards long, this all-white elastic can be inserted into a casing or stitched directly to the wrong side of your fabric—if using a non-stretch fabric, stretch the elastic to the length of the fabric while sewing. Using a stretch or zig-zag stitch is recommended. From PJ waistbands to pant cuffs, bralette straps to underwear waistlines, this elastic can conquer all.
