Removing Snaps

[seamstress52.livejournal.com]

Hi all
I made a wallet from a tutorial found at crafster but I used snaps instead of velcro.
It didn't really work. The cards fit in the slots when its open and all but it doesn't close right.
When I make more I'll make them longer so I can use snaps. They really are cute. See...



Before I go attacking it with all kinds of crazy stuff, what is the best way to remove snaps?
And can I reuse them when I'm done? And will the fabric be all crappy?
Thanks in advance.
