The prettiest girl baby quilt I've made so far was 3 taupe fabrics, 3 gray fabrics, 3 white on white fabrics and 3 pink fabrics for the pinwheels and the background was a small taupe, gray and white floral spray on a cream background. It was just stunning.
I only make pinwheel baby quilts. They're fast, easy and no two have ever been alike. I never use "baby" fabrics because kids tend to start rejecting things as "too baby" when they hit 2.5 to 3. Girls are especially bad about that.
