You can always catch a small break and slide it off you nail. Maybe just out tape across the tops, and a little bit at intervals along the side?
You could also make other forms of double backers. Splitting cards and using double stick tape or rubber cement on the inside is the best option. You can very easily just use double sided tape/rubber cement in between 2 cards, without splitting it.
Alternatively, use a glue stick. The only problem occurs if it is not used for a long period of time. At that point, you can maneuver it to crack the glue on the inside, making it soft again.
