Triple Irish Chain, Is a great idea!
I did a doudle for a friend many years ago with a yellow daisy fabric in the back ground with a peri winkle/ blue smaller daisy print with a white on white Love print Fabric.... Wish I took a pic.... anyway
The idea of a black and white is a great idea and adding thier favorite colors in a scrappy feel through the center chains? Using varying shades I believe you wont demasculate her groom to terribly <3 Keep us posted :)
