Thanks. I just got off the phone with my mom, an avid quilter. She also showed the pic to my uncle and cousin (who didn't see anything but pinwheels). Her idea is for me to use a dark pink thread and quilt around the center squares in a diamond shape connecting at the white strips' points on each outer side. Then I could add a heart or another diamond on the center square if I needed something else to help. She told me I'm very sensitive to it now since it's become an optical illusion and that's all I am seeing. But the dark pink thread would help to break up the white.
