Holey Seashells

[slybootz.livejournal.com]

Would any of you have suggestions on the best way to go about putting holes through various seashells (clam, oyster, etc.)? The FAQ didn't wield any results, but I noticed the Dremmel being mentioned for other items.

I checked out A.C. Moore and they had some sort of beadhole enlarging device, which looked like a motorized, pointy file. I don't know if that would be tough enough to make it through a shell, but you never know!

Thanks in advance :)
