Hello.  My intended use for this product is for dog collars.  But I am not intending on using this alone for dog collars.  I intend to sew marine upholstery vinyl to both sides and use the beta biothane as an inner strap.  I need something strong, not grooved, and something I can easily sew.    It has to be near the equivalent of about 5 oz. of leather.  Could you please contact me.  Thank you!
