Ok, so I have been lurking on Craftster for quite a while, but a penpal is worth breaking the silence for!
My name's Stephanie. I'm 21, and I live in lovely, mountainous Asheville, North Carolina. I moved here a bit over a year ago from my native Philadelphia. Moving's harder than most people tell ya... Right now I'm a full time student in a metals/jewerly program. I also work at a yarn shop (not the dream job it sounds like, but you gotta love cheap(er) yarn).
Crafty hobbies: jewelry making, knitting, crocheting, book-making, pie-baking, stuff-collecting in the hopes of stuff-making (does that one count? or make sense?)
Other hobbies: reading (though I'm quite a big fan of books on tape at the moment, since I don't sit still well), thrift shopping, travel (when possible, which is of course not often enough), movies (and I'm wierdly obsessed with movie reviews, too. what's up with that?)
To a mildly embarrassing degree, I'm a fan of snarky animated series (The Simpsons, Futurama, and so forth).
One of my next goals in life is to get a tattoo of Milo from The Phantom Tollbooth, then possibly one of a sea otter (why a sea otter? I just really like them---what, don't you?).
I own a hell-of-a-lot of ugly owl pendants from the sixties and seventies, and am still looking for a way to display them for maximum impact.
I'd love a pen pal from any background, really, and by email or the old fashioned way. Swaps could be fun too!
Nearest I can tell, your main concerns with these versus regular long chain earrings would be
1. The smoothness of the ends on the "threader" or the ends of the earrings and
2. The size of the chain used would have to be thin enough to be comy slidin' through your piercing.
It looks to me like those threader ends aren't head pins, but probly just wire tubing, filed all nice and smooth (you know, like the post part of post earrings is basically just wire). In this case, though, it looks like it's hollow. I know you can purchase tubing in some pretty small gauges ( you wouldn't want larger than 20 or so, for comfort's sake again).
These might be soldered, but a good jeweler's cement might work fine: just take the chain, add a bit o glue, thread into the tubing a bit to keep it secure. Then you can attatch your beads and prettiness to the other end.
As for the size of chain, go with whatever is just small enough to fit in the tubing.
