Very nice, Monica! All of my stamps are in SU! clear cases. I used Krylon's Easy Tack as the sticky to help the stamps stay on the clear blocks. But I've since decided I don't like the ET spray. I still have half a can and it no longer sprays out the spray the way it should. I saw a post where someone just cut out pieces of the thinnest clear vinyl and applied it to her clear SU! blocks. The stamps stick like a dream to the blocks and cling very well.
As I go forward, I will probably use this trick instead of spraying my unmounted stamps.
