You can get them at Walmart too, in the craft section.
We sell chain by the foot, and I generally send out a long chain of however many feet are ordered instead of cutting it into 12" sections. It never occurred to me that people may actually prefer to have it cut into 12" sections already. (I can be a little blonde sometimes!) If you ordered the chain from me, I apologize that I didn't think of that before.
I'll make a change to that on the website and have the option of a 12" length with a loop at the bottom and hanging hardware at the top.
