Since some of you asked, here's the skinny on charm bracelets...
I counted and I have 63 charms on my bracelet. And though Toben thinks I should start a new one, I think there's plenty of room for more charms! I love having it full and jingly. And, no, it's really not too heavy!
Here's a picture:
A great place to get charms, braclets, and charm bracelet info is My Charmed Life. Rings n Things also has a good selection of charms at a great price. James Avery also sells silver charms. (Sometimes you can find charms at Hobby Lobby or Michaels--but they're usually made of pewter, and sterling silver is really best.)
If you're buying a bracelet for a little girl, go ahead and get a bracelet that will fit her as an adult. Mine has a lobster clasp on it, so when I was small, I just attached the clasp to one of the loops rather than the end clasp to make it small enough to fit my wrist.
Charms can be soldered onto the bracelet--which usually costs about $10 a charm. Not cheap. So now I use split rings to put mine on. I bought a bag of 100 from Rings n Things for about $10. A much better deal. Of course, it's up to you. My mom still likes to solder all of hers onto her bracelet because it is stronger.
To find charms when you're traveling, you often have to go to really tacky, really fun touristy kinds of shops. These charms often have a little flag attached to them, telling you where the charm came from. But for bigger monuments like the Eiffel Tower or the Leaning Tower of Pisa, you can search the charm websites.
There are also charms for every hobby imaginable, as well as blank charms that you can have engraved. I have two little girl heads on my charm bracelet with Audrey and Emma's name on them and the dates they were born.
