Any chain fine enough to scale well with a
40k model is going to weigh very little, regardless of the material used, so I wouldn't worry about that overmuch. It will, however, likely want to drape naturally. If you want to keep them still, a tiny dab of thin
CA glue at the joints between links will do the trick. You can actually get some pretty dynamic effects by manipulating the chains while "setting" them. As far as procuring them is concerned, most craft stores carry usable ones (although I can only personally vouch for Michaels), as do online vendors (industry suppliers like Rio Grande, right down to small shops on Ebay and Etsy catering to the DIY market).
