Helene Knott spoke at our guild meeting this week on this very subject. Her theme was "color theory" and she showed some very interesting examples of taking the same colors and the same block and rearranging them. The results were so interesting. She showed an Amish quilt that had gazillion little squares, all the same pattern, but with different colors. The variance in color value (mostly) made a huge difference in the overall effect of the pattern. We can lay out our colors/swatches and say, "Oh. . I like those together." But then we must decide how to distribute them to get the desired effect.
