Do you guys put permanent margins on your screens? If so, how do you do it. I've been using a technique described in the "Screenprinting - the complete waterbased system" book by Adam and Robertson that involves gumstrip tape covered in acrylic paint, but it seems like everytime I go to degrease or decoat the acrylic paint starts warping/flaking/peeling. I feel like I'm spending too much time maintaining my "permanent" margins. What do you think?
