Hi Damkina:
First, congratulations to your family on this wonderful news! But you are right, now you have to get busy and make a quilt to commemorate their special day.
I came across this post as I was also looking for something for one of my students as she just got engaged. She was not ready for the traditional, so we are conquering this version together. I just ordered the book for her class and we go fabric shopping this weekend! Hope you like it and/or it helps to give you more ideas to think about.
