Unfortunately, I don't remember the beaded flower necklaces people made in the 60's even though I lived through them; I was pretty sheltered then.
One of the additions to my line of jewelry has been what I call "Jewelry for the Younger Set". Here's the URL to that page of my website:

I use less expensive components for these, so parents don't have to worry about their little girls losing expensive jewelry. If your special little girl is old enough that lead crystal isn't an issue, I'd use Swarovski crystal components for extra sparkle - but she has to be old enough to understand that she can't put her jewelry in her mouth.
Good luck and please let us know what you decide to make and how it turns out.
