The 3M mounting tape I use is thinner than the SU Dimensionals. I get it at the hardware store, $4.89 a roll. It's for mounting things outdoors, so heavy duty. It's about an inch wide. I like that I can cut it in long thin strips or short squares or whatever shape I want. I also like that it NEVER comes loose. But if I need to, I can remove whatever it's stuck to, without harming anything else on the card, by microwaving it for a few seconds to melt the glue. I start at 10 seconds and go up from there. The thicker the card stock, the longer it takes.
