craftgrrl | DS Cozies and 4mm Swavorskis?

I just bought myself a Nintendo DS that'll be here soon, and I'd like to make a cozy for it. It'll be more or less my first sewing project, but my mom went to FIT for fashion design so I have her to help me out if it's a little too complicated for a newbie.

I know some people have posted their DS cozies in the past, but with this community's high traffic I have no idea how far back they were posted, I just remember seeing them. Does anybody have any links for those posts or better yet, a pattern?

OH, ALSO! I used to be very into these 2-foot high resin dolls and I bought a lot of 4mm Swavorski crystals which were the perfect size for making jewelry for them. But now that I've gotten out of the hobby, I have a TON of these tiny crystals I'm not sure what to do with. Does anyone have any suggestions for them? They're these. I have lots of them in various colors.
