Brad and I really wanted to give Jillian some scriptures for her baptism. We didn't want to spend a lot of money on something that would get a lot of childhood abuse but then we didn't want something that would fall apart as a result of the aforementioned abuse. I was over at my friend, Kim's house and saw a paperback Book of Mormon with a very stylish cover on it and I thought, "that's perfect!!" So, she and another friend taught me how to do it and I set off to work. It does take a bit of time (to let the glue dry) but my finished cost was only $21, including the books! And, Jillian loves that they are girly and different from everybody else's. Here's what they look like:

Materials:
Paperback scriptures
Two 12x12 scrapbook paper for each book's exterior
One 12x12 scrapbook paper for each book's interior
Ribbon
Mod Podge
Directions:
Measure the book's face and binding width and length. Make sure you include an extra inch on each side so that the paper can be folded to the inside. Cut the paper out and glue it to the book using the Mod Podge. The paper should cover the book face and at least 3/4 of the binding side, with one inch left beyond the remaining three sides of the book. You will need to smooth this out with your fingers and a straight edge. Keep smoothing until all the wrinkles are out and then place a heavy object on top of the book until it dries. This makes the book very smooth. Repeat this on the back side of the book, only allow the paper on the binding side to stop midway across rather than 3/4.
When both sides are completely dry, cut out the corners of the paper and fold the hanging inch to the inside cover. With a paint brush, apply Mod Podge and press the paper down, making sure you wipe any extra glue off. I put a piece of wax paper between the inside cover and the first page so that the glue wouldn't stick while it dried. Repeat on the back side and then press the book again with a heavy object until the glue is dried.
If you desire, make a name tag. I printed this off my computer onto some card stock and then mounted it with the same color of paper that was used on the inside.
Brush the Mod Podge on each exterior side, allowing it to dry before turning the book over. There are several types of Mod Podge finishes; I used a matte finish. When each side is completely dry, measure, cut, and glue the ribbon onto the book. I used the ribbon down the side to cover up the paper seam. Cut enough ribbon so that it folds over the inside cover at least 1 and 1/2 inch.
Measure the inside cover. You want to cover up the exterior paper edges but allow at least a 1/4 inch border around the interior paper. Glue the paper down with the Mod Podge, wiping off any extra glue, then press with a heavy object.
You can decorate the books with different kids of brads (inspirational plaques, flowers, etc.) or connect the ribbon with a brad on each side and then have it tie at the book opening. Really, the sky is the limit. I wanted to keep mine simple since it was for a child. Also, if you get the Book of Mormon only, rather than the triple combination, you only need one 12x12 paper for the exterior.
