On one of my early baby quilts I sewed one panel--a quarter of the entire quilt--of a trip around the world 180 degrees from what it should have been. When I was quilting the quilt, the dominant fabrics were in diamonds as they were supposed to be. But when I started to quilt the non-dominant colors, they made a rectangle, not a diamond pattern!! I finally noticed that one of the four corner blocks was the wrong color. I finished the quilt and called it a geometry puzzle. The people I gave it to loved it so much they hung it on their baby room wall.
