Mobile Help PLEASE...

[azaspeaks.livejournal.com]

Does anyone have any suggestions on how I would go about hanging a circular "mobile". Like for a baby? I bought 2 styrofoam rings and covered them in fabric and fancy ribbons- and when I got around to the hanging part, the fishing line I was prepared to use just looked too TACKY. This is a gift, so I need it to look as neat as possible. How can I hang it now without ruining the fabric? The styrofoam rings are the kind you would use for a christmas wreath- like donuts. There is one medium sized one and one small one...
Please, please help!
