Sandy, here is a thought that may help with the corners. Try planning them first, then working your ribbon pattern from them towards the center line of each side. If the ribbons don't meat and match at the center correctly, adapt the pattern at that point. You could leave a solid space, create a complimentary motif, or anything you want. It will look balanced and the corners will be matched. When you get Elizabrat's you will see what I ended up doing. Should be in the mail tomorrow to you!
