The grayscale view of your fabrics shown by justwannaquilt shows the values of each fabric. I agree with the observations made by this board members. I do think 15 is not quite right in color but the value is fine. I also agree that 2, 3, 1 is a better value scale of light to dark that as presently shown. I am sure you will have a beautiful quilt that will be highly valued by the recipient.
