A must have for random quick fixes on fabric or fabric projects. I don't really use this for anything permanent but I am new to using a sewing machine so I sometimes mess up my hems. This works perfect with a little ironing the fabric is held together and I am able to sew it straight without pinning or clipping. This is also a good  product for a quick fix if your pants hem comes loose just iron this on and stitch it later when you have a spare minute.
