I have also tried the press-n-seal. At first it seemed to work just fine, but the 2nd time I tried it, I found that it gunked my needle up really bad and totally gave me fits. I now buy the golden threads paper & pin or glue dot on & sew thru, or sew through with an empty needle and pounce. On lighter colors, I have a light box and trace with sewline pencils before I sandwich-just be sure not to heat-set or they will likely become permanent.
