where to buy inexpensive solderable conductive thread (or fine wire for making my own)?

Anybody know good places to buy fairly inexpensive solderable conductive thread (or thin non-kinking wire for making my own)? I don't intend to use it in a sewing machine, my goal being just flexible without kinking. I'd like a nice selection of metal colors also if possible. The Karl Grimm threads are pretty, but I've no idea how to order some or how much they cost, but I'm guessing expensive.

I sell solderable conductive thread at my etsy store:
