Since this is the top, what better thing to add than the sky and the sun. Mountains in the background and of course, pine trees.
For the rule and technique, the sun is my pinwheel and it is needle turn appliqued behind the sky. I cut the circle and appliqued it by hand. From each seam of the pinwheel, I hand embroidered a sun ray. The mountains were fun to do. I have a pattern with one mountain with the snowcap, but it looked pretty lonely, so I added a couple more. For a block this size, it was a challenge to fill it in, and I may still add some more clouds.
