You're the only one who knows how you wanted it. Every one has their own way of doing things. I think it looks fine the way it is. As long as you don't say anything I think you're good to go. It's gorgeous the way it is. If it's custom order and the customer wanted the holly and berries on the sashing then yes you should change it. If it's fusible you should be able to remove with a bit of heat from the iron.
