I do think it is pretty. If I hadn't done those two rows with 5 hearts I would consider doing 3 in one row, two in the next, then three, etc., leaving a blank space between each one. I don't know if it is looking too busy or not after looking at it for months.
The blocks are all sewn into strips and I have two long sashing strips done and ready to sew together 2 sets of two blocks (like the top rows). Then I start working on the hearts.
Don't know if I am done for tonight or not, it's almost 8:30pm and need to eat dinner.
