This is Ami Krenzel's quilt, Echoes of Spring. It was the second place winner in the category Small Innovative pieced and/or appliquéd quilts.
Ami had blogged about it as she made it, so I recognized it immediately. Of course, it is even better in person. I love those organic improvisational curves and all that fabulous quilting.
Here's Ami's other quilt from the show, in the same category, Into the Woods.
