Well it's been quite a project. My piece for the large skirt is complete and so are the others! Here is a picture of the almost complete circle, it still needs binding sewn on...but it's just about ready to go. Mine is just to the right of the bottom. Aren't they all pretty!
There is also a 12' skirt for another large tree, this one is made up of panels of forest service posters that have been printed on fabric. Each panel also has a 9" quilt block inset. They are pretty simple, but look really great when all sewn together.
