What a special thing for you to do in making a quilt for a friend with fabric that she will love. I also love the Warm Wishes pattern--used it several times. However, the modabakeshop pattern will eliminate cutting those bunnies. Also, if you needed to extend the bunny fabric, you could use the piece of fabric that resembles "grass" and use it as part of the focus piece, or just as the border. You did not state the size you are doing. Just a suggestion.
These Board members are terrific and I love it when they put up the sites to patterns, etc.
