Can someone please tell me how to take an old hard wired light fixture and change it to a swag light? My [U]home office doesn't have any receptacle for a hard wired light, so I have to resort to swag/plug in lighting and want to use an old tiffany style light fixture but need to change it to a swag type hook up. The old fixture has about 2 feet of chain already attached. Please use VERY easy instructions as I don't speak "electrical"... Thanks!
