i did a stained glass window inspired quilt for my mother for chrismas. i used some cording stuff that looks like wide shoelaces which i got at the fabric store to make it look metal inbetween the 'glass' peices. it was actually alot easier than i expected it to be....
link to pic of mine to show you how the stuff looks on
