Great quilts! It's just amazing what happens when you take a so-so fabric and use it for a OBW!
And that Radiant Sunshine and Shadows quilt is fabulous!!! I LOVE those; even have the book, but haven't done one with the size blocks they suggest. I did use the same technique but with 2½" strips (so, yes my blocks were 3 times the size of yours), and liked the way that one turned out too.
