I've got the pendents I'm making, and I've got several new designs I'll be trying to make to sell. Problem I'm having is -- what do I put them on?

I would like to put them on something people would be happy to wear, like braided leather cords, but I'm not finding them cheap enough to make including one economical. At the price I'm selling the pendents for I wouldn't make a cent!

I'd rather not go up on the price of the pendents to include the cost of the cords, but I hate the prospect of selling a pending to someone who doesn't have a necklace to put them on. (I would also feel silly trying to sell a cord for nearly the cost of the pendents themself.)

Any suggestions on what I can use? I'd like to find something thick enough that it doesn't look like string. :P
