"Ova Nova" by Louisa Smith was a color study for her that utilizes oval shapes instead of circles.
Ova Nova features ovals, instead of the more common circles that Louisa likes to use in her quilts, as a way to see how one of her quilts would turn out utilizing this shape. Not only acting as a "What If?" type of design for Louisa, it also doubles as a color study that pulls different values from all across the color wheel. She says it was great fun to make.
