I won some Creative Expression stamps, and bought u foam mount to back it up with. I read the instructions and decided to follow! BIG MISTAKE. The instructions tell you to cut each stamp out then place it on the u mount foam, cut it foam out bigger than the stamp, then take the sticky side out, stick the stamp on. Then cut it again. Each U foam mount sheet can cover the back of 2 sets of stamps. Following their instructions is time wasting, and you get sticky scissors, and you will end up using two sheets for two set of stamps instead of one.
I found it easier to stick the whole of the stamp sheet onto the u foam mount - then, cut it out. No sticky scissors, and no cutting the image out three times.
