I know you are tired with your quilt, but maybe if you put it away for a couple of days and pick up another, perhaps simpler quilt/block to work on. When I get to the stage where I can't stand working on a project, I put it away, do something else, then I'm ready to come back to it. Your quilt is going to be beautiful, I love how you have the left upper lighter corner, going down to the darker right hand corner. I love the multi colored print fabric. I might put the darker color for a 3" border, then a 5" border (or larger) of the multi colored print fabric, or just the darker color. It's going to be beautiful when finished.
