There isn't one color in particular that reminds me of Harper, but there are color schemes that remind me of her. This is the crib set that I picked out for her so many months ago, in the room that would have been hers.
And this one is the quilt that Aunt Shelley made for her. She didn't know what the crib set looked like when she made it, but it has the same birds, and same lime green accent. I am just amazed how she made the three birds at the top to represent Steve, Joey, and me, and the one representing Harper was separate. It's just so perfect.
