Are we talking 100mm square filters?
I have this problem, and am not happy with my storage method. Currently in little plastic sleeves, in a padded Lee wallet.
Mine are also getting scratched a little bit. I don't believe this will affect the pics, but can increase the possibility of flare?
For my Cokin P filters I just got a Lowepro filter wallet from Jacobs in Liverpool.

How many filters can it safely hold? The 'View Larger Image' link is just so worth it.
