I get asked at fairs if they are for light cords in bathrooms! I say, you buy em, you can do whatever you want with them!
I'm the first to admit I'm not a jeweller and I do have friends that are and have turned them into beautiful pieces! I just like making them, once finished, I'm onto the next, so the bead is almost a leftover product of my love of making! Unfortunatly I still have to charge for that enjoyment!
