By nature, a pinwheel block looks like it’s spinning in the breeze as the triangle points lead your eyes around the block. Depending on which way you place the points, the block rotates clockwise or counterclockwise. Mix the block orientation on the same quilt, and you’ll create quite a stir!
Quilting designs inside the blocks can add to the illusion or they can help calm the winds, depending on their placement. The design in the photos below fit the orange triangle nicely. But its symmetrical shape keeps the attention focused on the triangle itself, not necessarily on the pinwheel block as a whole.
By contrast, the design in this quilt below is not symmetrical. It leans into the direction the pinwheel already seems to be turning, pulling your eyes along with it.
Symmetrical designs tend to capture your attention and keep it focused in a specific spot. These shapes often feel more traditional, but they can also call out piecing mistakes since the eye is looking for uniformity when it sees a symmetrical shape.
Symmetrical: made up of exactly similar parts facing each other or around an axis; having symmetry.
Asymmetrical: having parts that fail to correspond to one another in shape, size, or arrangement; lacking symmetry.
While an individual design can be symmetrical or asymmetrical, you can also place it symmetrically or asymmetrically.
In the diagram below, the 8-point star block itself is symmetrical. When an asymmetrical quilting design like the hook shape is flipped over on every other diamond, the quilting design also becomes symmetrical.
Notice how the design does not spin at all? Your eyes stay focused on the block itself. But did you also notice how your eyes migrate to the center of the quilting design, where all of the points come together? If either your piecing or your quilting isn’t spot on, the design will call attention to the problem instead of hiding mismatched intersections.
By contrast, asymmetrical designs create a feeling of movement; they draw the eye away from a specific spot. Asymmetrical designs are great camouflage artists, because they trick you into looking someplace else. If the piecing isn’t quite as precise as you wanted it to be, then an asymmetrical (or asymmetrically placed) quilting design can help hide it.
The quilting shape in diagram 2 below is the same one used in Diagram 1, but it is not flipped on every other diamond. Is the star spinning clockwise or counterclockwise? If you look at the hook shape in the wide part of the diamond, I’d vote for a counterclockwise spin. But if you
look at the outer tips of the quilting design, it feels like it’s spinning clockwise! And I’d bet that your first glance did not take you to the center of the star!
As you can see, in this diagram the star is spinning in the opposite direction.
When choosing a quilting design, you’ve got lots of things to think about: do you want the quilting to stand out or blend in? Do you want the thread to show or hide? Do you want the quilt lightly quilted or heavily quilted? When you ask yourself, “where do I want to focus the attention on my quilt?” experiment with symmetrical and asymmetrical designs as well as design placement. You might be surprised by where your imagination takes you!
