My daughter just finished a "baby" quilt which she donated to our Guild's charity program. It was black & white prints, several tone-on-tone grays and lime green prints. Not baby-ish in any way, but some new mom is going to love it.
I, too, like the second layout. I wouldn't worry about the corners matching. It will be stunning, and your grand will love it.
My daughter just made a new quilt for her daughter, and when she got it, she looked at her mom and said, "I love it, but I'm still sleeping with BoBo." That's the quilt I made for her when she was 2 weeks old. She is now 6 and can't go to sleep without it.
