My niece was married a few months back and came up with this idea to save her wedding cards.
Our family is very sentimental and will figure a way to save anything personal. To make a binder, center your cards with the rings and punch the holes.
Here is a photo of the open book. She has two binders full of wedding cards and invitations This will be a treasure for years to come. I love the idea that someone loved my card enough to include it in notebook.
This is a great way to preserve all the sentiments and well wishes from family and friends.
