I've been making banners out of vintage childrens books.
I've aslo used old sheet music, and I have comics and maps waiting to be made into banners.
I have found a way to improve upon my previous attempt at making banners and that is to laminate them! It gives them a more finished look and of course they will be more durable.
I hope people love them as much as I do or they might have to become permanet decor at our house and I'm not sure how Dave feels about that!
