I embossed a piece of medium brown card stock and then used a dark brown ink for the low lights and alternately used bronze and gold Brilliance pigment inks until it looked like an old fashioned ceiling tile. Then just shadow the edges with the darker color. It shimmered so nicely. Too bad the camera didn't pick that up better!
I made this card for my friend, Carol Ann, while she was battling cancer... miss you, Carol Ann!
