I’ve had several request for a tutorial on this birdhouse. Enjoy and get ready to fold , fold, fold!
I used an old hymnal but you could use any book. The more pages the fuller it will be. You will need to remove the cover. Sorry no photos. I usually take a razor and slit down the inside of the cover.
The first fold will be to take the top corner and fold it into the center spine. All pages will start with this fold.
Then take the outer edge and fold towards the spine. This will be the first of the alternating pages.
Again, the first fold for the second page starts as the first.Then take the bottom corner and fold it up to the center of the spine.
These two pages will be alternated for the whole project. 
After you get several pages done it should start to look like this.
After folding for what seems like forever, you’ll end up with this.
If you want your birdhouse to hang now is the time to hot glue a rope of desired length down the center of the spine. Then glue the first and last pages together.
I then use a circle punch and cut out half circles on several pages to make the hole. You could just paint a circle.
I then paint that area black.
The final touches are adding raftia to the hole and on the roof. I also add some paper birds that I make and wad up blue paper to make little eggs. Here’s a last look at the completed project. Happy Folding!
