Here is my first almost-finished repair. I had to go all the way out to the creme/white on this one. I'm hoping the existing cream will brighten up when I wash it.
Below, it's nearly done, except I have some big basting stitches through it holding some batting on the back (yet to be determined how do to THAT part!)
Here is the second rosette - again, I had to include 3 cream pieces. Also, more big basting stitches to hold it all together until I figure what to do for the back. Since all the damage is along fold lines, I might just put one wide blue piece across the whole thing.
