When I was taking painting lessons, one of the things I learned was that having a variety of values in a painting was very important. The same is true for quilting. If you are not sure there is enough contrast or change of value, there are two ways to check. One is to look at the painting or quilt sample through a red lens or film. What this does is give everything a red color so only the value changes are noticable. If there isn't much difference you know it would be best to change some of the values. The other way is to make a copy of the painting or quilt sample in black and white. Again same thing. Your looking to find light, medium and dark, not all one tone.
