Oh, how I lovvve getting letters in the mail! I love sending them too. Basically, how I see it is that a letter on white-lined paper is rather boring so I try to make my letters as cuuute and interesting as possible.
Also, why write only one letter? The more the better. This is the letter I sent Nina, (along with a few other friends).
It is a bundle of letters made out of post-its, sissors, white paper, and ribbon. It was inspired by the bundle of love letters in the NoteBook.
