Challenging project! Good for you. However, as noted in another reply, I would be careful about placing the yellows next to the cream. You'd need a very bright yellow to provide enough contrast. I have been guilty several times of being disappointed in the quilt because of lack of contrast in my colors. Everything just blends together until it's difficult to see the pattern. I'd try some sample blocks before plunging ahead on the quilt. Good luck! Very nice of you to make her a quilt.
