Designed for "stitchless sewing," Dritz Liquid Stitch is a non-toxic, permanent adhesive that's ideal for mending hems, attaching appliqués, applying patches, inserting zippers, and more. Just squeeze a few drops of Liquid Stitch from the easy-to-use applicator bottle, allow to dry for 30 minutes, and the job is done! Liquid Stitch is water-soluble until dry. After 24 hours, the bond is machine washable and dryable. Pre-washing fabrics before application is recommended.
