I did this for my husband a couple of years ago, I used stuff that I had on hand. I cut up an empty cereal box and covered it with scrapbook paper. For the rings I just wrapped wire and around a pen.
I love the wallet size pictures because I use the extras for stuff like this. I did a couple of different pages for each kid with pictures of them and their daddy.
The last page I let them draw or write a little message. Sienna was 2 months old, so I just did her hand print instead, and I'm so glad I did because, now I can't even believe that she was ever that small.
