Look at #9 the bottom right corner is the wrong fabric.
I had both of the blue Boston Stars laid out to sew together. I think probably the corner squares fell off my desk and when I picked them up I switched them and put the wrong one in each star. I did catch it in the first star #5 but just thought I'd grabbed the wrong fabric and cut a new square for that one.
I didn't notice that #9 was also wrong until I posted the pictures LOL The keychains are already on their way to the convention with my cousin so I can't fix it. Probably wouldn't go to the trouble anyway.
