Felted cd case?

[sea-cow.livejournal.com]

I'm thinking of making felted wool cd cases, just little pockets with a flap and a closure of some kind, probably velcro. The cd would be inside a cardstock folder inside, so it wouldn't come in direct contact with the wool. Does anyone know if the wool could still harm the cd in any way? Would it build up a static charge or something? Maybe cotton would be better?

Follow-up question: These would be sent out to prospective employers with some work samples on the cds. I'm still deciding if that's a dumb idea, since my job doesn't have anything to do with knitting, but it might set me apart from other applicants. The question is, do you think it would set me apart in a good way (Hey, this girl's creative, let's hire her) or a bad way (This weirdo sent a cd cozy)?

Thanks for any advice or opinions.
