OK, I knew the center square needed "something" so I set to work on it, adding more the the appliqued grapes and embroidering a stem. Then I wanted to embroider a berries motif on it as well, and couldn't find a pattern to use. So, I did freehand drawings of the berries with a non-permanent marking pencil and set to work embroidering them as well, which I enjoyed doing very much. Now, it's finished! But, I plan to add some of the same touches to some of the quilt squares to tie it all together.
