I made one just like yours at a quilting class in 2010 at Joann's. My husband loves lighthouses and he helped me when I had a few issues with putting it together. Mine is just a little smaller. I don't remember the size. Mine is 5 blocks across and 5 blocks down. When I was making it, I was not real happy with it at the end. I think I was tired of making it. Now when I look at it, I love it. It looks nice when it's in the lighting in my home. I only stitched in the ditch.
I think your quilt and the quilting look beautiful.
