Okay I just checked and the wire that I got before (that didn't work) was Southwire coated copper wire (the kind of stuff you normally use for wiring to TVs and stuff). There was a 12 on the package so I thought that meant it was 12 gauge wire but I really doubt it because of how easily it bent under the weight of the fabric, which is nowhere near the strength of the white coat hangers I found in my closet, which you say are around 20 gauge.
I'll try and go back tomorrow--so OOK is the brand I should look for? I'm just bummed I can't return the other stuff since I already cut it but at least now I know for the future.
So I just found this online--something like this? http://www.homedepot.com/p/t/1002009....U PIjnWfNmSo
