I used a roll of craft paper for the base structure and it worked beautifully. I used three pages from an old calendar to get the images, but you can use anything, or just draw your own images. I hope you will be inspired to try this project.
1. Choose images.
2. Cut and fold craft paper (8" x 30") and lay out images.
3. Cut holes in pages so you can see through the tunnel.
4. Pasted first image and cut in an oval around elements you want to keep.
5. Paste down the other images and glue side tabs together.
Finished tunnel book with 4 layers of images.
