Your quilt is stunning. I know it was a lot of work, but you did a fabulous job of expanding the design! I understand about fitting it to a specific mattress size. I had the same problem with a quilt for my grandson and had to add an extra wide border: Traveling Turtles Quilt. Once it is on the bed, the main focus will be on the top. I think either the peach or the red swirl would look great. What color is her room?
