TUNNEL BOOK

Tunnel Book

This was supposed to be a sample, but I liked it enough to add a cover, so at least it's a pretty sample.
Begin with two accordian pleated sides of the same size.  Add panels of the same size with centred cut outs of decreasing size.  (I used nesting dies).
I put a piece of mirror board at the end, so you can look down the tunnel and see yourself!  If you're more arty, you could make a scene with different features on each layer.
