Well, to cut a long story short, I COULDN'T! I just had to add silver (Is silver a colour? It is, isn't it...). So it doesn't really count as an all-white card, but I like it anyway. (Although it was extremely hard to do it justice when I was taking the photos.) Now I just have to wait for someone I know to get married!
