Narrow glue marker allows for a more precise application. Blue air-soluble ink shows where glue has been applied. Color fades as glue dries. Any remaining glue washes out. Soak lace or similar product to completely remove glue if necessary. NOTE - Always test glue on a swatch of fabric to be sure that it can be removed satisfactorily before using on your project.
