What cute baby quilts! I love how the animals are looking down at the sail boat in the block below them. Your green and white is just sweet, so delicate. And the blue and white one, with a bit of red, looks so comfortable. All are great. Your Hunter's Star quilt is beautiful, and so is your Warm Wishes.
You do good stuff! As for borders, I'd go with dark for the Hunter's Star and I'd probably put that green as the last border in your Warm Wishes.
