charm necklace question - type of chain?

This is a big problem for me so any help is appreciated. I use the
double link cable chain for charm bracelets, but I'd like to find a
good chain for charm NECKLACES. I use dangling alphabet letters so
the double link 5mm links works well because the letters/jump ring
sort of "lay" in the pocket/groove of that type chain and the letters
don't fli over.

Can anyone tell me a good type of sterling or silver plated chain to
use for a charm NECKLACE?

Thanks so much. The double link chain by the foot is hard to find
plus with the cost of silver it's very expensive and eats up all my
profit. Silver plated is fine for what I need - I just need it to
work with alphabet charms. Feel free to email me directly at
is you prefer.

Thanks so much.
