Thanks, everyone!!!! Wouldn't you know it, I forgot to take "final" finished pics before I gave them to her. I will try to remember my camera next time I go see her. (My ex-MIL, by the way - she's a very dear friend, and today is her b-day!)
I ended up not being able to find 12" square pillows, but I got 14" square. So, I added a border a shade darker than the darkest blue already on the block, and then for the back side I made a 12" friendship star block with the same kind of border as the front. I was really pleased with the way they turned out! Especially for my first!!!
