i've used sa*an wrap (are we allowed to name names?) and had success. i don't use tiny stitches. i used a blue pen and a purple pen. they both worked. one disappears and one washes out. i wash my quilts anyway, but i don't remember any bleed-through.
try it on a sample and see what size stitch you'll need and if you like that look.
pull the plastic off slowly.
btw, if you have mid- or long- arm, you can use the plastic to create new pantos by tracing over anything that looks like a design that you don't have to lift the needle for.
