The answer is patently no! Even the addition of a few half square triangles and flying geese couldn't help. Then I remembered there were half a dozen wonky houses I had made some time ago, waiting in my UFO box. I added them, along with more half square triangles made into diamonds and pinwheels, and suddenly, we have lift-off!
That's more like it! It was quite tricky to join together, but a bit of adjustment here and there and it all went together in a very satisfactory way.
Here is the finished top (alongside some books of DD's waiting to go to the charity shop!) which is bright and cheerful, and joining the pile waiting to be quilted.
And here is my small orphans box, not even half full. A result!
