I don't like the purple - i think it's too light for the outside border..I feel like the quilt is "unbalanced"....My eye wants to see a darker color on the outside. Think of a stack of something - the "heaviest" item is on the bottom - for me, I think the visually "heaviest" item should be on the outside.
What about repeating the pink polka dot on the outside??? darker shade of purple?
